Write a C++ program to check the largest number among three given integers

#include <iostream>
using namespace std;

int test(int x, int y, int z)
        {
            int result = max(x, max(y, z));
            return result;
        }
        
int main() 
 {
  cout << test(1,2,3) << endl;  
  cout << test(1,3,2) << endl;  
  cout << test(1,1,1) << endl;  
  cout << test(1,2,2) << endl;  
  return 0;    
}
