Git is a distributed version control system DVCS designed for efficient source code management, suitable for both small and large projects. It allows multiple developers to work on a project simultaneously without overwriting changes, supporting collaborative work, continuous integration, and deployment. This Git and GitHub tutorial is designed for beginners to learn fundamentals and advanced concepts, including branching, pushing, merging conflicts, and essential Git commands. Prerequisites include familiarity with the command line interface CLI, a text editor, and basic programming concepts. Git was developed by Linus Torvalds for Linux kernel development and tracks changes, manages versions, and enables collaboration among developers. It provides a complete backup of project history in a repository. GitHub is a hosting service for Git repositories, facilitating project access, collaboration, and version control. The tutorial covers topics such as Git installation, repository creation, Git Bash usage, managing branches, resolving conflicts, and working with platforms like Bitbucket and GitHub. The text is a comprehensive guide to using Git and GitHub, covering a wide range of topics. It includes instructions on working directories, using submodules, writing good commit messages, deleting local repositories, and understanding Git workflows like Git Flow versus GitHub Flow. There are sections on packfiles, garbage collection, and the differences between concepts like HEAD, working tree, and index. Installation instructions for Git across various platforms Ubuntu, macOS, Windows, Raspberry Pi, Termux, etc. are provided, along with credential setup. The guide explains essential Git commands, their usage, and advanced topics like debugging, merging, rebasing, patch operations, hooks, subtree, filtering commit history, and handling merge conflicts. It also covers managing branches, syncing forks, searching errors, and differences between various Git operations e.g., push origin vs. push origin master, merging vs. rebasing. The text provides a comprehensive guide on using Git and GitHub. It covers creating repositories, adding code of conduct, forking and cloning projects, and adding various media files to a repository. The text explains how to push projects, handle authentication issues, solve common Git problems, and manage repositories. It discusses using different IDEs like VSCode, Android Studio, and PyCharm, for Git operations, including creating branches and pull requests. Additionally, it details deploying applications to platforms like Heroku and Firebase, publishing static websites on GitHub Pages, and collaborating on GitHub. Other topics include the use of Git with R and Eclipse, configuring OAuth apps, generating personal access tokens, and setting up GitLab repositories.

Introduction:
In geometry, a triangle is a three-sided polygon with three angles. Right angle triangle is a special type of triangle which has one angle of 90 degrees. The area of a right angle triangle is half of the product of its base and height. In this article, we will discuss how to calculate the area of a right angle triangle using C++ programming language.
Problem Statement:
Write a C++ program to calculate the area of a right angle triangle, given its base and height.
Solution:
To calculate the area of a right angle triangle in C++, we need to take two inputs from the user: base and height. After that, we will use the formula for the area of a right angle triangle, which is half of the product of its base and height.
Let's see the code:
#include <iostream>
using namespace std;
int main()
{
float base, height, area;
cout << "Enter base and height of the triangle: ";
cin >> base >> height;
area = 0.5 * base * height;
cout << "Area of the triangle = " << area;
return 0;
}Explanation:
In the above code, we have used the `iostream` library to include the `cout` and `cin` objects for input and output operations. We have also used the `using namespace std;` statement to avoid the prefix `std::` before the objects.
Then, we have declared three float variables `base`, `height`, and `area` to store the values of base, height, and area respectively.
Next, we have prompted the user to enter the base and height of the triangle using `cout` and read them from the keyboard using `cin`.

After that, we have used the formula for the area of a right angle triangle, which is half of the product of its base and height, and assigned the result to the `area` variable.
Finally, we have printed the value of the area of the triangle using `cout`.
Testing:
Let's test the program with some sample inputs.
Test Case 1:
Enter base and height of the triangle: 5 4
Area of the triangle = 10
Test Case 2:
Enter base and height of the triangle: 10 12
Area of the triangle = 60
Test Case 3:
Enter base and height of the triangle: 7.5 6.2
Area of the triangle = 23.25
All the test cases are working fine and giving the correct output.
Conclusion:
In this article, we have discussed how to calculate the area of a right angle triangle using C++ programming language. We have used the formula for the area of a right angle triangle, which is half of the product of its base and height. We have also tested the program with some sample inputs and found that it is working fine.
