Copy constructor with pointers

Question

I have recently discovered that when I have pointers within a class, I need to specify a Copy constructor.

To learn that, I have made the following simple code. It c

More often than not, if YOU need to write a copy constructor or assignment operator you're doing something wrong. Leave the copy constructors and assignment operators to the implementers of the standard library. Compose your classes of already-copyable and assignable elements and you won't have to write your own.

For example, maybe that int * member should be a std::vector instead.

If you can't make the class default copyable/assignable, maybe you can make it non-copyable/assignable by declaring, but not implementing, a private copy constructor and assignment operator.

Only if none of the above are feasible should you implement your own copy constructor or assignment operator.
