# Sum of Digits of a Five Digit Number | hackerrank practice problem solution

__ Problem:-__

The modulo operator, `%`

, returns the remainder of a division. For example, `4 % 3 = 1`

and `12 % 10 = 2`

. The ordinary division operator, `/`

, returns a truncated integer value when performed on integers. For example, `5 / 3 = 1`

. To get the last digit of a number in base 10, use as the modulo divisor.

Task

Given a five digit integer, print the sum of its digits.

Input Format

The input contains a single five digit number, .

Constraints

Output Format

Print the sum of the digits of the five digit number.

Sample Input 0

10564

Sample Output 0

`16`

__Solution:-__

#include <stdio.h>

#include <string.h>

#include <math.h>

#include <stdlib.h>

int main() {

int n,r,sum=0;

scanf(“%d”, &n);

//Complete the code to calculate the sum of the five digits on n.

while(n!=0)

{

r=n%10;

sum=sum+r;

n=n/10;

}

printf(“%d”,sum);

return 0;

}
