C program to print an integer

In this article, you will learn how to print an integer value on the output screen in C programming. Here, the printing of an integer is implemented in two programs:

Print an integer in C

To print an integer value in C programming, use the printf() function with the %d format specifier, as shown here in the following program. The %d format specifier is used to output numerical data.

#include<stdio.h>
#include<conio.h>
int main()
{
    int num=10;
    printf("Integer Value = %d", num);
    getch();
    return 0;
}

This program was built and runs in the Code::Blocks IDE. Here is its sample output:

c program print integer

The variable num is declared (of the int type) and initialized with 10. Print its value using the %d format specifier.

Print an integer entered by the user

This program receives an integer value from the user at run-time and prints the same on the output.

#include<stdio.h>
#include<conio.h>
int main()
{
    int val;
    printf("Enter the Value: ");
    scanf("%d", &val);
    printf("You entered %d", val);
    getch();
    return 0;
}

Here is its initial output:

c print integer entered by the user

Now enter any numerical value, say 20, and press the ENTER key to see the following output:
