Sum of all integer divisors of a number

I want to find sum of all divisors of a number i.e. if the number is 6 i want to have 1+2+3+6=12. My attempt to approach it is:

#include <iostream>

using namespace std;

int divisorsSum(int n){
int sum=0;
for (int i=1; i<=n; i++){

return sum;

int main()

However surprisingly it does not work at all, it returns nothing and i am not able to figure out what is wrong with my code.

Thus the question is how to make it works?
BTW: There is no point in immediately downvoting everything I am not an exper and yes i do make mistakes.

Answer Source

You have several issues in your code.

int i = i;

and i is still not defined. You probably wanted i = 1

i = sum + i;

sum is not updated above. You probably wanted sum += i
