C Program to Print Hello, World!

This is the first program most beginners write when learning C programming. It simply displays the text 'Hello, World!' on the screen using the printf() function.

Concept Overview

In C, the `printf()` function is used to print output to the console. The program must include the header file `stdio.h` (Standard Input Output Header) to use printf(). Every C program begins execution from the `main()` function.

Program

C
#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}

Output

Hello, World!

Explanation

  • `#include ` – Includes the standard input-output library required for using printf().
  • `int main()` – The entry point of every C program.
  • `printf("Hello, World!");` – Displays the message on the screen.
  • `return 0;` – Indicates that the program ended successfully.
Note: Note: Every C statement ends with a semicolon `;`. The output is printed inside double quotes using printf().
