printf function

When the c program needs to communicate with the user, We should use printf function.

The communication can be,

"welcome to c program"

"Enter your username/password" etc.

printf function is defined in stdio.h header file.

So if we want to use the printf function in our c program, we should include stdio.h header file.

Syntax of printf

printf("");

It will print characters to the screen which is given inside the double quotes "" .

And it should end up with a semicolon ;.

Example

printf("Hello World");

printf("Enter two numbers");

printf("Bye");

Example

#include<stdio.h>     //header section 

int main()             //main section 
{
    printf("Welcome to the C Programming");

    return 0;
}

The below program has some syntax errors.

Correct the program by yourself and see the output.

Example

#include<stdio.h>

int main()
{
    printf("Correct me!)

    return 0;
}
