Message: [QUOTE="Kai-Uwe Bux, post: 2581389"] Why? Many of the answers to the questions below will depend on your reasons and design goals for the Vector class. Generally: do not roll your own Vector class: std::vector<> is there for a reason. I can only think of two valid reasons to roll your own std::vector<> replacement: a) You want to learn how it's done. b) You need to use vector<T> for an incomplete type T or a type that for some other reasons does not fullfill the requirements of std::vector<> (e.g., T might be copy-constructible but not assignable). Then, you need an implementation that makes stronger niceness guarantees than the standard requires or works around such limitations in some other way. call that push_back(). don't try that. Is this supposed to remove all elements of a given value? Do you really want to remove by value or do you want to remove at a certain position. Are you sure you are designing a vector? Could it be that you are Yes. Well, at least you need to be clear about who the owner is. Yes: use std::vector. If you really need your own, try to mimmick std::vector as closely as possible. In this case: take the arguments by const reference and use the copy constructor to copy them. Best Kai-Uwe Bux [/QUOTE]
