Question

#include <iostream>
using namespace std;

int sum(int a=4, int b=2) {
int result = a + b;
return (result);
}

int main() {
int x = 24;
int y = 36;

cout << sum << endl;

//calling the function with both parameters

return 0;
}

Answer 1

In your comment you've mentioned about calling function with both parameters 😐
So, the correct function call should be
sum(x,y) or sum(). The outputs should be 60 and 6, respectively.

Answer 2

If you make the function call properly, the answer should be 60

Answer 3

You forgot the braces () after sum:
cout << sum() << endl;

Answer 4

Answer 5
