C Program To Find Sum of Digits Of An Integer

Here we will write a program to find sum of all the digits of an integer using looping

#include<stdio.h>

int main() 

{
  int n, sum=0, rem;
  printf("Enter the no : ");
  scanf("%d",&n);

    while(n!=0) 

{
  rem=n%10;
  sum+=rem;
  n/=10;
}
printf("Sum of digits  = %d ",sum);
return 0;
}
