Write a C Program to compute the Sum of the digits of an integer.

#include<stdio.h> 

void main()
{
   int n,i,remainder,sum = 0;

printf("Enter an integer : \n");
scanf("%d", &n);

i = n;

   while (i!= 0)
   {
      remainder = i % 10;
      sum       = sum + remainder;
i         = i / 10;
   }

printf("Sum of digits of %d = %d\n", n, sum);
getch();
}
