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...

A function can only return one parameter. You could i suppose return a pointer to an array or struct of data though.

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 ") { 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...
