Mmh, and I forgot to remove the template :
#include <iostream>
#include <sstream>
#include <vector>
#include <string>
using namespace std;
class Foo {
private:
int x;
int y;
public:
Foo(int xv, int yv)
: x(xv)
, y(yv) {};
friend ostream& operator<< (ostream& os, const Foo& f);
};
ostream& operator<< (ostream& os, const Foo& f) {
os << "(" << &f << ") = Foo(" << f.x << ", " << f.y << ")";
}
int main() {
Foo f(1,2);
cout << f << endl;
}
