Write a C++ program to compute the sum of the three integers. If one of the values is 13 then do not count it and its right towards the sum

#include <iostream>

using namespace std;

int test(int x, int y, int z)
        {
           if (x == 13) return 0;
           if (y == 13) return x;
           if (z == 13) return x + y;
           return x + y + z;
        }
        
int main() 
 {
  cout << test(4, 5, 7) << endl;  
  cout << test(7, 4, 12) << endl;  
  cout << test(10, 13, 12) << endl;  
  cout << test(13, 12, 18) << endl;    
  return 0;    
}
