    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
    Ivan

    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);

    Talking

    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
