Virtual Destructors

• Every time you use a new, you want to be sure you have a matching delete.

• You also want the destructors to be called in the proper order.

• If you didn't make the base class destructor virtual, it would be the only one ever called.

• By making it virtual, a Brass Plus object calls a Brass Plus destructor (default) first and then calls the base class destructor second, insuring proper order!
