C Program To Calculate Sum of Digits Using Recursion

A 5-digit positive integer is entered through the keyboard, write a recursive and a non-recursive function to calculate sum of digits of the 5-digit number.

Analyze The Problem Statement
1. User enters a 5-digit number.
2. We need to write 2 functions to calculate sum of digits of user entered number.
3. One function should use recursive logic and the other should calculate sum of digits without using recursion.

How to print repeated numbers with out using array with the help of nested for loop please tell me

[kunsangmoktan]

#include<stdio.h>
int d=0, res=0;
int sum(int n){
if(n == 0)
return 0;
else
{
d = n % 10;
res = d + sum(n/10); this should also work right but is not working and giving different output
return res;
}
}
int main( ){
int n;
printf("Enter a number: ");
scanf("%d", &n);
printf("Sum of digits are %d", sum(n));
return 0;
}

the above logic is not working, please help
