In this tutorial, We will see the example of input and output function in C programming language.
C Output
In C programming, printf()
is one of the main output function.
Example: C Output
#include<stdio.h>
void main()
{
printf("C Example"); //Displays the string
}
Output
C Example
How does this program work?
To use printf()
in our program, we need to include stdio.h
header file using the #include <stdio.h>
statement.
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.
C Input
In C programming, scanf()
is one of the commonly used function to take input from the user.
Example: C Input
#include<stdio.h>
void main()
{
int number;
printf("Enter a number: ");
scanf("%d", &number);
printf("Number = %d",number);
}
Output
Enter a number: 10
Number = 10
Here, we have used %d
format specifier inside the scanf()
function to take int
input from the user. When the user enters an integer, it is stored in the number variable.
