overloaded operators

Hi!

Has anyone done much with overloaded operators.

I've got a '<<' and a '+' which work fine but when I try to do,

cout << a + b;

it says no match for ostream& << MYCLASS

'<<' is a friend and a+b accepts parameters by value ad returns by value (not reference)

Has anyone seen anything like this before?

Thanks

OK,

FYI

// this wouldn't work for cout << a + b;
friend ostream& operator<< (ostream& out, MyClass &obj);

// this works for cout << a + b;
friend ostream& operator<< (ostream& out, MyClass obj);

When you overloaded your + operator what value are you returning??

you're going to have to paste a bit of code before i can help you.. please paste your operator+ and operator<< routines.

thanks
