C Program to Read Integer from User and Print It

In this article, we will learn to write a very simple program in C that will ask for an integer number from the user’s console. After hitting enter, The number will be shown as “You entered: number”.

So we need some very basic concepts of the C programming language to write this program. The simple I/O functions (scanf for input, printf for output), the main function structure.

Algorithm – Print an Integer read from user

  • We will simply ask and print a number in the main function.
  • In the main function, we will declare a variable called myInt, and the type of the variable is an int – as we will keep the integer number in the variable.
  • Ask for an integer number from the user using the scanf() function and then keep in the myInt variable.
  • Finally, print the myInt variable using the printf() function with the preferred format.

C Program to Print an Asked Integer Number

#include <stdio.h>
int main() {
    int myInt;
    printf("Enter an Integer: ");
    scanf("%d", &myInt);

    printf("You entered: %d\n", myInt);
    return 0;
}
  1. Now run the program using your favorite text editor or IDE to see the output in the console like the one below.
Sample Input Sample Output
Enter an Integer: 56 You entered: 56
Enter an Integer: 102 You entered: 102
