Write a C Program to Compute the Sum of Digits of a Given Integer

Saroj July 12, 2022

In this tutorial learn how you can write a c program to compute the sum of digits of a given integer.

We are using a while loop and some maths tricks for this tutorial. Some tricks are below:

Given integer % 10 to get the last digit.

And Given integer / 10 to remove the last digit.

And repeat the process through the while loop.

C programming is a powerful general-purpose programming language. It can be used to develop software like operating systems, databases, compilers, etc.

Write a Program to Compute the Sum of Digits of a Given Integer

Here is the code to compute the sum of digits of a given integer in C programming. 

#include <stdio.h> //WAP to calculate  factorial of  a number.
int main()
{
    int num, i, fact = 1;
    printf("Please enter any integer:");
    scanf("%d", &num);
    for (i = 1; i <= num; i++)
    {
        if (num <= 0)
            printf("The factorial not possible");
        else
            fact = fact * i;
    }
    printf("The factorial of %d is %d.", num, fact);

    return 0;
}
