Thread: more than one return parameter

I am having problems finding infromation on using the &x I know how it is used... I am just wondering about general functions that return more than one parameter, looking for practical examples...

I mean &x pointers, for instance one example I have is adding, subtracting, and multiplying 2 different numbers, and having the results returned... but I need other practical examples

Here's a simple example.

Code:

#include <iostream>
using namespace std;
int main()
{
   double a, b, s, d, p, q;
   cout << "Enter two numbers:";
   cin >> a >> b;
   calculate(a,b,s,d,p,q);
   cout << a << "+" << b << "=" << s << endl;
   cout << a << "-" << b << "=" << d << endl;
   cout << a << "*" << b << "=" << p << endl;
   cout << a << "/" << b << "=" << q << endl;
   return 0;
}

void calculate(double a, double b, double &sum, double &dif, double &prod, double &quot)
{
   sum = a + b;
   dif = a - b;
   prod = a * b;
   quot = a / b;
}

thanks for example... but that is the one I already have... I was looking for other practical examples...
