Program to find the sum of the digits of a number – Coding Question 9

Write a program to find the sum of the digits of a number.

#include<stdio.h>

int main()
{
int num,temp,sum=0,r;
printf("\n Enter a number: ");
scanf("%d",&num);

temp=num;

while(num!=0)
{
r=num%10;
sum+=r;
num=num/10;

}

printf("\n Sum of Digits of %d= %d",temp,sum);

return 0;

}
