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.

In C programming language, we can use the scanf() and printf() functions to take input and output data respectively. In this article, we will write a C program to print your own name using these two functions in two way.

Example 1: In this example, we print the user name using printf() function.

// C program to demonstrate printing of
// our own name using printf()
#include <stdio.h>
  
int main()
{
    // print name
    printf("Name : Codegyan");
    return 0;
}

Output : 

Name : Codegyan

Example 2: In this example, we use scanf() to accept the name as input from the user and then print it.

Here's how the program will work:

  1. We will declare a character array to store our name.
  2. We will then use the scanf() function to take input from the user and store it in the array.
  3. Finally, we will use the printf() function to print the name that we just stored.

Here's the complete code:

// C program to demonstrate printing of
// our own name using scanf()
#include <stdio.h>

int main()
{
    char name[50];
    
    printf("Enter your name: ");
    scanf("%s", name);
    
    printf("Your name is: %s\n", name);
    
    return 0;
}

Output :

Enter your name: Codegyan

Your name is : Codegyan 

Let's break down the code step by step:

  1. We start by including the stdio.h header file which contains the scanf() and printf() functions.
  2. We then declare a character array name of size 50. This will be used to store the name entered by the user.
  3. We then use the printf() function to display a message on the screen, asking the user to enter their name.
  4. We use the scanf() function to take input from the user and store it in the name array.
  5. Finally, we use the printf() function to display the name entered by the user. The %s format specifier is used to indicate that we are printing a string.

That's it! When you run the program, you will be prompted to enter your name. Once you enter your name and press enter, the program will print it on the screen.

It's important to note that the scanf() function is susceptible to buffer overflow attacks if the input exceeds the size of the buffer. Therefore, it's a good practice to use the fgets() function instead of scanf() when taking input from the user. However, for this simple program, we can use scanf() without any issues.

In conclusion, this program demonstrates how to use the scanf() and printf() functions to take input and output data respectively in C programming language.
