Returning multiple values from a function using references

  
#include <iostream>

using namespace std;

enum ERR_CODE { SUCCESS, ERROR };

ERR_CODE Factor(int, int&, int&);

int main()
{
   int number, squared, cubed;
   ERR_CODE result;

   cout << "Enter a number (0 - 20): ";
   cin >> number;

   result = Factor(number, squared, cubed);

   if (result == SUCCESS)
   {
      cout << "number: " << number << endl;
      cout << "square: " << squared << endl;
      cout << "cubed: "  << cubed   << endl;
   }
   else
      cout << "Error encountered!!" << endl;
   return 0;
}

ERR_CODE Factor(int n, int &rSquared, int &rCubed)
{
   if (n > 20)
      return ERROR;   // simple error code
   else
   {
      rSquared = n*n;
      rCubed = n*n*n;
      return SUCCESS;
   }
}
