Early examples redesigned

Using new and delete, the Stash example introduced previously in this book can be rewritten using all the features discussed in the book so far. Examining the new code will also give you a useful review of the topics.

At this point in the book, neither the Stash nor Stack classes will “own” the objects they point to; that is, when the Stash or Stack object goes out of scope, it will not call delete for all the objects it points to. The reason this is not possible is because, in an attempt to be generic, they hold void pointers. If you delete a void pointer, the only thing that happens is the memory gets released, because there’s no type information and no way for the compiler to know what destructor to call.
