Thread: how is it possible to return multiple values?

Two ideas:

Code:

#include <utility>
#include <iostream>

std::pair<int, int> myfunc() {
   return std::pair<int, int>(0, 1);
}

int myfunc(int& ret) {
   ret = 1;
   return 0;
}

int main() 
{
   std::pair<int, int> x = myfunc();
   std::cout << x.first << ',' << x.second << '\n';
   int tmp;
   int y = myfunc(tmp);
   std::cout << y << ',' << tmp << '\n';
}

There are a lot of other ways: Pointers, passing / returning a vector that holds the results, etc. Of course, if the returning values are of different types, then you'll most likely have to use references, or a struct similar to pair (Like C++0x's tuple)

Or return a structure if you want to return a number of variable types.

using pointers is probably your best bet.

theres a nice quicklink to a pointer tutorial if you need it.
