7.4.5.Returning multiple values from a function using references
#include <iostream>

 void f(int, int&, int&);
 
 int main()
 {
     int number = 2, squared, cubed;

     f(number, squared, cubed);
 
     std::cout << "number: " << number << "\n";
     std::cout << "square: " << squared << "\n";
     std::cout << "cubed: "  << cubed   << "\n";

     return 0;
 }
 
 void f(int n, int &rSquared, int &rCubed)
 {
      rSquared = n*n;
      rCubed = n*n*n;
 }
 
number: 2
square: 4
cubed: 8
