Introduction

Congratulations on starting your journey into C programming! `Hello, World!` is the traditional first program that beginners write when learning a new programming language. In this tutorial, you'll create your first C program, which will display `Hello, World!` on the screen.


Writing the `Hello, World!` Program

Open a text editor and create a new file, and then enter the following C code:

#include <stdio.h>
int main() {
printf(`Hello, World!\n`);
return 0;
}

This code is a simple C program. It includes the standard input/output library (stdio.h). The program defines a main function, which is the entry point of every C program. Inside the main function, the printf function is used to display `Hello, World!` on the screen. Finally, the return 0 statement is used to indicate that the program has run successfully.


Compiling and Running the Program

Now that you've written the code, you need to compile and run it:

  1. Save the file with a .c extension, such as hello.c.
  2. Open your command prompt or terminal.
  3. Navigate to the directory where you saved hello.c.
  4. Compile the program using the following command:
gcc hello.c -o hello
  1. Run the program using this command:
./hello

If everything is set up correctly, you should see `Hello, World!` printed on the screen.


Conclusion

Writing and running your first C program is a significant milestone in your programming journey. `Hello, World!` is the first step in understanding the basic structure of C programs and how to compile and run them. From here, you can explore more complex C programming concepts and applications.
