In this tutorial, you will learn how to write a C program to print an integer entered by user. This is a very simple program. You just need to capture the user input using scanf, and store it in an int variable, then you can use printf to print the value of the variable.
C Program to print an integer
#include <stdio.h>
int main() {
int number;
printf("Enter an integer: ");
// reads the user input stores in 'number'
scanf("%d", &number);
// print the 'number'
printf("Integer entered by user: %d", number);
return 0;
}Output:
Explanation of the above program:
This is how a variable is declared, since we want to store an integer number so we have declared the variable as int. The variable name can be anything, however it is good to choose a meaningful simple name:
int number;This line displays a message to the user to enter a number:
printf("Enter an integer: ");Entered number is scanned and stored in variable number:
scanf("%d", &number);Finally the value of the variable number is displayed:
printf("Integer entered by user: %d", number);
