First program in C language.

First program in C language.

C Programming include   #include< header file>  stdio.h include printf , scanf.

#include is a way of including a standard or user-defined file.

<stdio.h> std - standard library, i - input, o- output, h- header.

The main function serves as the starting point for program execution. It usually controls program execution by directing the calls to other functions in the program.

The printf() is a library function to send formatted output to the screen.

#include <stdio.h>   

int main()

{

    // Displays the string inside quotations

    printf("C Program");

    return 0;

}

Output

C Program

How does this program work?

 

All valid C programs must contain the main() function. The code execution begins from the start of the main() function.

The printf() is a library function to send formatted output to the screen. The function prints the string inside quotations.

To use printf() in our program, we need to include stdio.h header file using the #include <stdio.h> statement.

The return 0; statement inside the main() function is the "Exit status" of the program. It's optional.
