Write a C program to find the sum of digits.

            Hi viewers , We are going to include a number of viewers required programs and information in our blog. kindly stay connected.

       Today , I am going to explain how to write a C program to find the sum of digits . What does the sum of digits mean ? If you consider a number say , 975 , the sum of its digits are - (9+7+5) = 21.
How to write a C program for this ? Let's see that now.

Note : In order to compile a C program , you need a C compiler. If you don't have kindly download it from here.

Source code:

#include<stdio.h>
int main()
{
int num,sum=0;
printf("Enter the number");                    // Accepting input from user scanf("%d",&num);
while(num>0)                                             //Loop to find the sum of digits {
sum=sum+(num%10);
num=num/10;
}
printf("Sum of digits is %d",sum);            //Print the result to the user return 0;
}

Output:
