Nope. You want to return the 'this' pointer because then you can do: Point TestPoint, TestPoint2; TestPoint = TestPoint2 = Point(1.2, 3.5, 5.0, 1.6); NOTE: You aren't returning anything from the overloaded operator. _However_, you don't need to define a copy constructor nor an assignment operator for the class because you aren't messing with pointers (and even if you were, you could get around that by using smart pointers). The compiler will define that functionality automagically for you. As an interesting side note, I haven't written a single copy constructor/assignment operator in the past 6 months. Safe C++ pretty much eliminated the need for that sort of stuff. -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 *NEW* VerifyMyPC 2.5 Change tracking and management tool.
