What is Machine Learning?

Machine Learning is an important aspect of computer and applied mathematics and computation where new discoveries are happening on a weekly basis. Machine Learning provides machines the ability to learn and improve without being explicitly programmed to.

Instead of knowledge driven approach, machines follow data driven approach to solve problems.

Using techniques of machine learning, we can nurture machines to perform classification, predictions, recommendation etc.

For a programmer to build a career in artificial intelligence and machine learning, he/she should have a profound knowledge of mathematics, statistics, programming (especially python or R) and machine learning. The core of every machine learning algorithm is based upon statistics and solving optimization problems using calculus.

At first we perform some data processing and analysis on the raw training data and then fed it to the machine learning algorithm, the algorithm trains a model that learns from the given data and evolve over time when fed with new data. Once the model is trained we fed the model the test data and the model takes decision based on the patterns is has learned from the training data.

The way machine learning works is as follows:

  1. We find the appropriate data for a relevant task and then perform some data analysis and the clean and preprocess the data.
  2. We pick up the best machine learning algorithm based on our analysis of the data.
  3. We train the model on the training data and compute the model accuracy.
  4. Then we perform hyperparameter tuning on the model which assures more accuracy score.
  5. We productionize the model using any web framework.

Machine learning is having wide range of application across industries. Not only tech companies but machine learning is used extensively in finance, medicine and banking. The world needs more machine learning engineers and data scientists at this moment.

Machine Learning Types

Machine learning is categorized into three different types. There include:

Supervised learning

The majority of practical and real world machine learning uses supervised machine learning. In supervised learning we use both the input and the output variable of our data. Given the data, we can easily find out a function that knows the mapping between the input and output variable. Any supervised learning machine learning algorithm can discover the function, then we tune the hyperparameters to get the best possible results. This process is called supervised because all of the output variables of our training data supervise the learning process of the particular machine learning algorithm.

There are two types of problems that we can solve by using supervised learning technique.

  1. Classification problems.
  2. Regression problems.

Unsupervised Learning

In unsupervised learning we only get the input variable in our training data, we don’t get any output variable. The goal of unsupervised learning is to group together the same kind of points and here algorithms use various advance techniques to find the patterns between same kind of data points and group them together to form a cluster.

Unsupervised learning problems can be of two types:

  1. Clustering.
  2. Association.

Semi-Supervised Machine Learning

In Semi supervised machine learning we get training data where only some of the input labels have their corresponding output labels. These problems position themselves in between supervised learning and unsupervised learning. A large set of real world machine learning problems fall into this area where most of the output labels are missing. Here we use supervised learning techniques learn and discover patterns in the training data.

One idea is to use a supervised learning technique to classify the labels of the unlabeled output data for certain input data points.

Essential Tools for Machine Learning

Anaconda

Anaconda is free and open source distribution of of the python programming language for data science and machine learning applications. Anaconda comes with all of the modern machine learning tools. It has the set of standard python libraries and bunch of other third party libraries like sklearn, SciPy, NumPy etc.

Our experts use anaconda tools extensively and we also advice our students to use it for most data science related work. Jupyter notebook is the most used IDE used in data science which comes pre-installed with Anaconda.

Essential Libraries for Machine Learning

NumPy

NumPy is an open source numerical python library. With the help of NumPy we can easily various advanced mathematical operation on arrays. NumPy is written in C and it’s very fast when it comes to perform large computation. NumPy provides the best implementation of mathematical operation with very low time complexity.

SciPy

SciPy is free and open source library for Python which is used for scientific computing and technical computing. It can be used for linear algebra, integration, interpolation, signal and image processing.

Matplotlib

Matplotlib is the most popular library that is used extensively in data visualization.

Matplotlib is the 2D plotting library in Python. To generate plots, histograms, bar charts and scatterplots, Matplotlib is used extensively . Not only we can plot various plots in matplotlib but we can also customize it according to our needs. We can easily plot various probabilistic plots like PDF, CDF using this library and make sense out of it.

Our experts use seaborn as well to visualize the data as seaborn is sometimes better.

Pandas

Pandas is the Python library for data analysis. It is the tool for reading and writing data. It has fast and efficient object design called DataFrame, high performance on merging and joining the data sets and time series functionality. Pandas is extensively in data science.

Scikit-learn (sklearn)

Scikit-learn is an open source project. It contains a number of machine learning algorithms. It is the most popular tool and prominent Python library for machine learning.

Except the above, we use NLTK for natural language processing, gensim for performing word2vec, seaborn for data visualization, pickle for saving a model etc. It’s kinda hard for someone to have knowledge of that many libraries and that comes with experience. Fortunately, most of our programming experts are working as a data scientists and they possess all the knowledge of these libraries. They can easily implement any complex task as they know what library is capable of doing what. Many students ask for machine learning assignment help which requires use of different libraries, our programming experts can easily help them out.

Machine Learning Algorithms

Linear Regression:

linear Regression is actually a regression technique. Given a dataset we predict the class labels in a classification problem while in regression we predict a real value as we don’t have class labels in a regression problem. Linear regression algorithm tries to find a line(in 2D)/ plane (in 3d) / hyperplane ( when the dimension is more than 3) that best fits the datapoints.

Assume, our training data is “D” consisting of “n” points and our dataset has “d” features. “D” consists of our X’s and Y’s and we have to predict Y where Y is a real number.

Suppose, we were given a dataset of height and weight where given a person’s weight we have to predict his/her height.

Here, our X is weight and Y is height. After we have our dataset, we can easily plot all of our datapoints in a 2d plane where x-axis represents the weight of the person and the y-axis represents the height of the person. The algorithm discovers a line that best fits all our datapoints and minimizes the squared loss. Where the squared loss is the square of the difference between actual Y and the predicted Y over all the datapoints, to be more precise we can easily minimize by GD or SGD algorithm.

Logistic Regression:

Logistic regression is one of the most widely used supervised learning algorithm. Even though logistic regression has “regression” in it’s name but it’s actually a classification technique. Logistic regression can only solve two class classification problem, we can also use logistic regression in multiclass classification problem in “One vs rest” setting. Logistic regression assumes that the data is linearly separable and we can separate the datapoints by discovering a line(in 2D), plane (in 3D) and hyperplane (in more than 3 dimensional space). It is worth mentioning that the dataset must get column standarized before modelling.

Assume, our dataset is “D” consisting of “n” points and our dataset has “d” features. “D” consists of our X’s and Y’s and we have to predict Y where Y can only belong to a certain class.

The way logistic regression works is as follows:

1. At first it discovers the line (in 2D) The best plane maximizes the sum of signed distances such that one side of the line contains data corresponding to one particular class and on the other side of the line we have datapoints corresponding to another class.

2. But maximizing the sum of signed distances is not outlier prone, to avoid this problem we use the sigmoid function. There are many other function which we can choose but specifically we choose sigmoid function because it gives a helpful probabilistic interpretation.

3. Then we multiply the function by a “-” and take the log of it to turn it into a monotonic function. Earlier we had to maximize the the optimization problem but we we have to minimize the optimization problem as we have multiplied it with a “-“.

4. Then we just solve the optimization problem and the solution gives us the the ubit vector which is normal to the plane, once we get the unit vector we can easily find the equation of the line/hyperplane.

Logistic regression is useful when the dimension is very high and it’s not just a black-box model but it’s also interpretable.

Decision Tree:

Decision tree is a very useful supervised learning technique where we build a tree based model from the given Data. Decision tree works best when the dimensionality of the data is small. In most of the cases decision trees are used in classification problem, but there’s also a decision tree regressor available.

We can think of decision tree as a simple “if-else” statement model and the decision surface of decision tree is axis parallel lines/planes or hyperplanes.

Starting from the root of the tree, the data is split on the feature that gives the highest Information gain. We repeat the process and stop when we get a leaf node. As the depth if the tree increases, the model overfits. Decision tree models are interpretable when the dimensionality of the dataset and the depth of the tree is low.

Support Vector Machines or SVM:

Support vector machines is a very powerful supervised learning technique.Linear SVM assumes our datapoints is linearly separable and it tries to discover a line or hyperplane that separates our datapoints as widely as possible. In SVM we minimize the Hinge loss and SVM works very well even on those datasets where logistic regression fails as it uses the kernal function in the dual form formulation of SVM. In high dimension space SVM transforms the features using the Radical Basis Function or in short RBF kernal. If some certain datapoints is not separable in low dimension space SVM uses the kernal trick to make it separable in high dimension space.

In the softmax formulation of SVM in we just tries to maximize the distance between the line / hyperplane and the datapoints. But when we use kernal SVM we must have to choose the right kernal. And how we choose it depends upon the machine learning problem we are solving. Basically for most of the problem RBF kernal works like magic but there are some edge cases where it does not work perfectly, when the situation occures we use domain knowledge to design the right kernal.

In Linear SVM our decision surface is a line or hyperplane but in kernal SVM it is non-linear surfaces.

Naive Bayes (NB):

Naive Bayes is a classification algorithm based upon the fundamental of probability but specifically Naive Bayes uses “Bayes theorem” extensively. Naive bayes can easily solve multiclass classification problems and it assumes that every feature in our datapoints is independent and mutually exclusive. Naive bayes can not solve regression problems.

Assume, our dataset is “D” consisting of “n” points and our dataset has “d” features. “D” consists of our X’s and Y’s and we have to predict Y where Y can belong to multiple classes.

The way naive bayes works is as follows.

Given a datapoint, we want to find out the probabilities of the datapoint belonging to every possible class. Then we take the largest probability of the point belonging to a particular class. While computing the probability using bayes theorem we ignore the evidence and only care about the likelihood and prior of the bayes theorem. We ignore the evidence because the value of the evidence remains constant. Then the algorithm solves the numerator of the bayes theorem and by using the MAP rule or Maximum the posterior rule picks up the class that has the highest probability.

Naive Bayes uses Laplace smoothing to handle some edge cases.In real world, Naive bayes works very good on textdata. In spam classification naive Bayes can give nearly 98% accuracy.

KNN (k-Nearest Neighbors):

K-nearest neighbors is one of the most popular supervised learning algorithm. KNN can solve both classification and regression problem and it’s extremly powerful when we have very few features in our dataset.

Assume, our dataset is “D” consisting of “n” points and our dataset has “d” features. “D” consists of our X’s and Y’s and we have to predict Y where Y can only belong to a certain class or it can be a real value. For simplicity suppose we have only 2 features in our dataset.

The way KNN works is as follows.

Step 1: If we have 2 features, we will plot the points in a 2 dimensional space.

Step 2: Then given a query point, we basically look at the k’th nearest points and pick up the class label by performing majority vote in a classification setting. For regression we take all Y’s of K points and pick up the median or mean value of it.

But how do we find the right “K”? At first we set k = 1 and compute the accuracy score, then we keep on increasing the value of K. After a certain value of K, the accuracy score will not increase but decrease. Then we pick the K value where the accuracy is high. We always choose an odd value for “K” as it may happen that we have equal number of class labels if “K” is even. When “K” is equal to “n” then the model underfits and when “k” is 1 then ithe model overfits.

k-means:

k-means is a type of unsupervised learning algorithm, which is used for unlabelled data. K-means is the simple and easy way to classify a given data set through a number of clusters where k is number of assumed clusters. In k-means we have clusters and each cluster has its own centroid. Here is the way how k-means works:

k-means picks k number of points for each cluster known as centroid.

Each data point forms a cluster with closest centroid. Finds the centroid of each cluster based on members in that cluster. Repeats this step to find new centroids.

Finds closest distance for each data point from new centroids. Associates it with new k-clusters.

Checkout the definitions of some of the machine learning assignments we have solved.

Random Forest:

Random Forest is one of the most popular supervised learning algorithm and it uses decision trees as it’s base model. We can also extend the random forest algorithm and the extended version is called Random Forest Regressor which solves regression problems.

Assume that, our dataset is “D” consisting of “n” points and our dataset has “d” features. “D” consists of our X’s and Y’s and we have to predict Y where Y can belong to multiple classes or it can be a real value.

The way random forest works is as follows.

1. In Random Forest we perform sampling. From the dataset “D” we randomly sample rows and columns and build decision trees on top of it. We break up our dataset into small datasets of “m” columns and “c” columns. Where n>m and d>c.

  1. Then we build decision trees on top of each dataset, here we don’t want our decision trees to have a lot of levels instead we want them to be shallow.

3. Random forest uses aggregation and in classification setting we typically take the majority vote to predict the classlabel. For regression task we can use mean, median to determine the right output Y.

Random forest is the most popular bagging algorithm and it’s works really good on real world dataset. It does not work good when the dimension of our dataset is high. When the dimension is high we typically choose Logistic regression or SVM.

Dimensionality Reduction:

In Exploratory data analysis we try to find out the relationship between the features of the data and we do it by plotting the data in 2D, 3D and by doing pair plots or even looking at the distribuition of the features of the dataset. But, What if our dataset has 784 dimensions? How do we visualize in that case? Dimensionality reduction helps us extensively in that case and there are two major dimensionality reduction technique,

1. PCA or Principle Component Analysis

2. T-SNE or T distributed stochastic neighbourhood embedding.

PCA:

In PCA we at first perform column standardization and then we try to discover the best unit vector that minimizes the squared of the distance of all the points from that unit vector. The direction of the unit vector is the direction where the maximum variance is available and the unit vector is actually the eigen vector that corrsponds to the maximum eigen value. We use two eigen value and their corresponding eigen vectors when we want to transform data from higher dimension to 2D space. That is basically how PCA helps us to visualize high dimensional data and typically PCA works good but not best!

T-SNE:

T-SNE stands for T-distributed Stochastic Neighbor Embedding. The neighborhood of a point is basically those points who are close to that particular point and embedding means we take points from high dimensional space and place them in low dimensional space while preserving the neighborhoods. T-SNE is an iteratrive algorithm and and it gives us two hyperparameters that we can tune, they are-

1. Perplexity

2. Step

The preferred perplexity value is 5-50 and the step is basically the number of iteration, as the step increases the clusters go away from each other and after a certain number of iterations it does not move much.

Feature selection:

The method of selecting the most important features for a classification or regression task is called Feature Selection. As the dimensionality increases the performance of our model decreases due to the “curse of dimensionality”. So, it will be very useful if somehow we can reduce the dimensionality and use the most important features only. But, How do we select the most important features?

We do it using a idea called Forward Feature Selection.

Step 1: We train a model for every single feature and test it’s accuracy on test data. We pick up the feature(suppose f1) which gives us the best accuracy score.

Step 2: We again train bunch of models by using f1 and every single feature except f1. Thenwe compute it’s accuracy on test data and pick up the best two features which gives best accuracy.

Step 3: We keep repeating the process and at some certain point we will have the number of

important features we want.

Feature Selection is independent of what model we choose to solve our problem. But one disadvantage of Feature selection is that the time complexity is pretty high.

  • Method of Dimensionality Reduction
  • Principal Component Analysis (PCA)
  • Linear Discriminant Analysis (LDA)
  • Generalized Discriminant Analysis (GDA)

Most of the students order us to develop the python machine learning assignment solution using Jupyter Notebook as IDE and as per their needs we choose the best tools that fit the certain problem. Typically for data analysis and pre-processing we pick up NLTK, Sk-learn, matplotlib, re and Seaborn.

We provide fully commented solutions with visualization and the code we write is very readable. Completing your assignment is not our main purpose, we also make sure that you understand the solution. Our experts use advanced libraries to solve problems where the code has very low time complexity.

When it comes to solving assignment problems, our experts make sure that the model get the best accuracy, recall and precision scores. The more the score, the better the model. We care about each and every thing that can be helpful to you.

We have developed solutions for lots of machine learning assignments and homeworks in Python. Please visit our page Python Assignment Help for more details about different types of Python assignments.

CHMOD 775 , CHMOD 755 Meaning – Managing File Permission with CHMOD

chmod 775

chmod command is one of the useful commands in user and file management (especially script files). Here we are going to explain to you chmod 775 , 755 & File permissions 

File Permissions in Linux using Chmod

As you know the file system of linux has a file access and control mechanism which determines how and who can access a file stored in a linux system. This mechanism is based on two parts i.e. namely Classes and Permissions.

Classes determines who can access the files while Permissions decides how the file can be accessed to the user.

Types of Classes in Chmod

Three types of classes exits in linux i.e. Owner, Group, Others.

  • The owner is the creator of files / folder in linux. By default all the file and folders you create are owned by you, until you change the permissions manually.
  • The Group consists of multiple users who share same permissions and user privilege.
  • Others means the general public.

Permission Types in Linux

Next is permission , which are of three types based on a file or Folder, which you can either read, write or execute.

  • Read :- One can read a file but they can’t modify the contents. In case of Folder , you can see the files inside Folder, but you can’t delete or add files into folder.
  • Write :- Here you can modify file contents & in Folder you can delete and add files into the folder.
  • Execute :- This permission allows one to run a file (mainly script).

If you combine the use of class and permission , you can control users on how they can access a file and what actions they can do or what they should not.

This can be understood by an example i.e. Owner has all the permissions (read, write and execute) to access a file. So if aren’t the owner of file /folder then you have to change the permissions to get the owner access to the file. The ownership of a file can be changed to any user as per requirements. The web server may won’t allow you to upload a file , in this case you are not having the enough permissions to add a file in a folder.

Chmod Number assignment

Now I expect you got the basic concept of classes and permissions , so we can go forward to the number i.e. “775” & “777”.

The file and folder is having a 8-bit data that controls the permissions mechanism. The basic binary form is “000” which means no permissions to any form.

  • As you set the “Read” permission , it adds 4-bit data which makes it “100” or a 4 in the usual decimal format.
  • Granting a write permission adds 2 bit data i.e “010” or 2 in decimal form.
  • Adding a “Execute” permission adds 1-bit to the data, which will result in “001”, or “1” in decimal form.

Numbers assigned to Read , Write & Execute

In other words

  1. Read is equivalent to ‘4’.
  2. Write is equivalent to ‘2’.
  3. Execute is equivalent to ‘1’

So as u decide to set permissions , we have to add the numbers. For example if we set permissions to read and write , then its like 6 (4 + 2) for the permission. For read, write and execute, we will use ‘7’ (4 + 2 + 1) for the permission. Here’s the different permutation:

Chmod All Combinations

  • 0 – no permission
  • 1 – execute
  • 2 – write
  • 3 – write and execute
  • 4 – read
  • 5 – read and execute
  • 6 – read and write
  • 7 – read, write, and execute

Using the numbers you can grant permissions to a file and add the numbers accordingly. So just understand this the three digits are “777”. First digit is for Owner, second or Group and third digit is for Others. If you assign “777” for a user then you can give all permissions for a file to all users.

String  Permissions it provide
755It is used in web server. The owner of file has all the permissions but all two i.e. Group and Others have permission to read and execute,they can’t make changes to the file.
777This number provides all the permissions of file to all three types of users. Every user can read , write and execute the file. It allows the users to add any type of code to your file. This is mainly applicable to the images in a website.
644The owner can read and write while every other can only read it. No other can execute the file too.
655The owner can read and write but can’t execute the file. Everyone except owner can read and execute but they can’t modify the file.

Setting File Permissions in Command Line

Linux lets you set all the file permissions by right click on the folder and by selecting “Properties”. The permission tab will let you assign permissions to the Owner , Group & Others.

The other way is terminal , where you can change the permission via Chmod. If you use chmod 777 that means you assigned all the permissions i.e. to make file readable, writable and executable by everyone.

chmod 775 /path/to/file

chmod command uses & Explanation

chmod is a command to change permission of a file. It stands for change mode. The number “775”  is to provide permission to the file. There are three type of permissions.

  1. r stand for read .its value is 4.
  2. w stand for the write.its value is 2.
  3. x stand for the execute.its value is 1.

If you assign a user 7 , then you are giving them read, write and execute permission to the user. The remaining part is 75 , which is explained here.

Example to Understand Chmod 775

If you enter a command  ls -la or ls -li or ls -l , any of these commands will  show all the files like this.

 drwxr-xr-x 2 amiss amiss 4096 Jan 29 09:48 Templates

Here d stands for directory as templates is a directory.

now rest remaining 9 character.

  1. The first 3 characters are owner means whom created this file , so he has all the permissions i.e. rwx (read , write , execute).
  2. The next 3 characters is for group. The group can have one or more users whom are giving permission for a file as decided by you. The group has execute and read permission but they can’t write it.
  3. The last is for other users i.e. permission for the read and execute.

So basically if you do 775 , then you are assigning same permissions to the owner , group and other users for a particular file which is written above.

Command for change the file permission in Linux – Chmod 775 syntax

chmod 775 filename

Hope the article helps you to understand the concept of permissions in a Linux system and the meaning of “777” & “775”.

A very unique feature that makes it different from other Linux OS. Tools that can encrypt a file, partition or whole drive.Like this there are many other anti-forensic tools which can be used by businesses to secure their data.

Pandora’s Box

This tool is a very useful tool for a forensic expert. As you know the data used by computer is stored in RAM temporarily & get erased after the computer is shut down. The statement above is false partially. Pandora’s box is a tool that is used by the forensic expert to recover the data which was on the RAM after shutdown. This can disclose all the details or tasks that were done by the previous user.

This tool will ask you to opt for the data to store secretly when the user is going to shutdown the system.This tool can be activated by the Super User only.Pandora’s box can remove the data from RAM if required.

RAM only surfing

This is a browser called iceweasel that will surf Internet but will provide any access to your hard drive. The data you will access in the browser can not be seen to other users. But still there will a question that the data in RAM can be accessed , Pandora’s Box will look after this.

Anonymous Surfing

There is tool known as Anonsurf which helps in surfing Internet without leaving any traces of your Identity. This is done by TOR browser. All the traffic of the user will be directed by TOR browser. In India, TOR networks are active, so the anonymous surfing can be done easily. It will also hide your DNS via TOR.

Penetration Testing

Penetration testing is one of the critical testing of a software or network. This type of testing helps the hacker to know about the anomalies in the system. After he will knew about the bugs in that system He can help the system owner to increase the security towards it. While this information can be used in some unethical ways too. I won’t suggest you to think like that.

There are many tools by which pen testing can be done. Some of them are packet sniffer,man in the middle attacks, brute force attacks etc. If you are familiar in using Linux then you must know about the tools used in Kali & Backtrack linux, the it would be very easy to switch on to Parrot Linux.

This is a very summarized introduction about Parrot Linux. This will help the users to know more about the Parrot linux. In the next section. I will be telling about the installation of Parrot Linux.

C++ is a powerful and flexible programing language which is used to for developing games, operating system, browsers and so on. And because of that, a computer science student needs to master in c++ language. Whether it is a college student or school going students everyone gets c++ homework.

C++ homework is given by the teachers to test the understanding and knowledge of students. learning c++ language is very important to become a professional programmer. Therefore, students must pay attention to their c++ homework so that they don’t miss anything important.

C++ programming help

As students already have a lot of other work to do they don’t have enough time to do c++ homework. It is very important for students to do their c++ homework not only to get good marks but also to get a good grip over programming language.

There are various online platforms that provide c++ programming help to the students. Anyone who feels short on doing his/her homework can get help from there. Doing c++ programming requires experience and application-based coding knowledge which students lack. Therefore, they need someone who can assist them in doing their c++ assignments. 

C++ help

To get a good grade in computer science and acquire good command over c++ a student needs help from a mentor. Without it, he or she would not be able to complete his/her assignment on time. Having a mentor is a boon for students as he/she can impart the concepts that a student miss or doesn’t understand fully.

A student needs someone who can work round the clock to help him/her in c++ programming language. Someone who would write optimized and effective code with minimal complexity order. It is very difficult to find someone in person who can do this but there are many mentors who are available online to help students in their c++ programming.

c++ code help

There are various subtopics that come under c++ code which students should know about to complete their c++ homework. A mentor knows about them completely, and that helps a student in learning and coding c++.

The following are the subtopics of c++ that are important to learn about.

  • C++ flow control
  • C++ functions
  • C++ arrays and sting
  • C++ structure
  • C++ object and class
  • C++ Pointers
  • C++ Inheritance

Along with that, it is also important to have a good understanding of the relation between class and objects, dynamic memory allocation, abstraction, exception handling, STL templates, inheritance, file handling and so on.

Often, students are not good at all these concepts and because of that, it becomes really hard for them to finish their assignments or homework on time. The real test of coding lies in testing how one can write a program using minimum codes. And that’s where a student needs the help of an expert.

C programming language project homework procedures

To do C programming language project homework, a student, first, need to decide which game, software, or application he/she has to develop. Once it is decided it will become a bit easy to start writing codes. To develop software or game it is important to utilize functions, data structure and file handling effectively. Therefore, students need to learn about them and practice them so that they could use all the functions of the programming language effectively.

In case, a student has no idea about how to write codes to develop software he or she should take help from a mentor who is available online. There are various online platforms that provide c programming language project homework, some of them are free while some are paid.

Basic c programming language projects are:-

  • Calendar Application
  • Cricket Score sheet
  • Customer Billing System
  • Hangman Game
  • Hospital Management System
  • Pacman Game

These are examples of mini c programming language projects. Students can easily find the programing codes of these software online.

C++ homework help Reddit

Reddit.com is also one of the great platforms to get help for completing c++ homework. There are many experts available here who can help students in learning c++ programming language. Students just have to post their questions on reddit.com and the experts would answer all of their queries.

Examples and references are also provided on reddit.com that help students immensely in learning a particular language and coding. 

My assignment help

There are two types of assignment help are available online. Partial help is for those candidates who wish to be helped by a mentor only in some cases or on certain things. This kind of assignment help is cost-effective and is very effective for those students who have a keen interest in learning and improving their programing language skills.

A complete help is an option available for those students who don’t have enough time and programming knowledge to complete their assignments. This kind of help is sometimes expensive as mentors work relentlessly to complete students’ assignments.

Urgent programming assignment help

In many cases, students need someone who could help them in completing their programming assignments on an urgent basis. To write optimized and effective code for the assignment work requires great skills and programming knowledge. And writing it in less time requires experience and good command over the functions of the language which a student lack.

Therefore, students should consult with an expert and professional programmer who could assist them in programming assignments and projects. Writing code is not a big deal anyone with basic knowledge of programming can do it. But writing codes with minimal use of codes is a tiresome activity and doing it on an urgent basis makes it even harder. Therefore, taking help from the expert is advisable.

C++ homework help

C++ homework mostly comprises significant phases such as flowchart, XML diagrams, blueprint designing, algorithm designing, pseudo code, and coding and testing developed projects. It is important for the success of a programing project that all the stated phases are performed properly.

The online platforms that provide help for completing programming projects and assignments are best for students. Students not only get their homework done by a mentor but they also learn lots of things which they may not learn otherwise. Because of these online platforms, students can easily get in touch with an expert who could help them in finding the solution to their programming problems. Now, students can focus on other important things without worrying about their c++ homework and assignment as these things can be done by someone else.

Pay someone to do my programming homework

As it is already mentioned that there are two types of help are available. The first is partial and the second is complete. In both types of help students need to pay some amount of money to the mentor to do their homework or help them in completing their homework.

Partial help is less expensive as compare of complete help because there would be selected things which would be done by the mentor and the rest of the work would be done by the student himself. To get a partial help, students need to browse through the internet and select an online platform which suits them best. And then pay for the plan you choose and get in touch with a mentor, simple, isn’t it? 

The second help is complete programming homework help. The procedure is the same for the complete help also but a student has to pay more for this. There are various plans available online for complete help as well, select the one which suits your budget and need. Pay for the plan and get the help to complete c++ homework.

C homework

To become a professional high-end programmer, it is important that first, a student acquire a basic knowledge of programming. C programming language is one of those programming languages that are a must to learn in order to become a software developer or game developer.

Merely learning this language is not enough, practicing and using all its functionality is also important and for that purpose, homework is given by the teachers. The more students get involved in their c homework the more they learn about the programing language.

It also helps students to get good grades in their exams if they learn and practice all the functions of the c language. Later they may get the benefit of it when they choose to pursue their career in programming.

Do my school C++ project for me

Online mentorship is available for those students who find it difficult to complete their school c++ homework and projects. Because most of the students are not interested in programming and don’t intend to pursue their careers in this field, online platforms are best to help them get good grades in schools.

Now, students can focus on things that interest them most. C++ project can be completed by hiring a mentor who has good experience and programming knowledge. What all a student needs to do is just find an online platform which provides best c++ homework services and choose a plan which suits him/her, pay and get the c++ project done by an expert.
