Wrong in the cout(functions)

[Antria4]

I can't find the wrong in this code i think i have a small problem at the cout but i don't know how to solve my problem . Can anyone help me and tell me why this is wrong ?

#include <cmath>
#include <cstdio>
#include <vector>
#include <iostream>
#include <algorithm>
using namespace std;

int sum (int a,int b);

int main(){
int c,d;
cin>>c;
    cin>>d;
cout<<sum(c+d)<<endl;
}
int sum(int a,int b){
int result;
result=a+b;
return result;
}

Your function takes 2 integers, you're only giving it one.

cout<<sum(c+d)<<endl;

change it to -

cout<<sum(c,d)<<endl;
