copy constructor issues with vector class

[nuzzle]

Newbie c++ student here.

As C++ is often taught it's easy to get the impression that writing copy constructors, copy assignment operators and even destructors is very central to C++ programming. It's not. One can in fact argue that these constructs preferrably should be avoided alltogether, especially if you're using the object oriented programming style in general high-level applications. So once you've passed the exam the best you can do is to forget about them. Quite a relief isn't it.
