This assignment (#6) is designed to make sure that you UNDERSTAND everything necessary for the next assignment (#7) which is a PROGRAM.  The program for assignment #7 will perform the same operations as Program #5 except instead of manipulating ints it will be capable of manipulating any data type using a generalized CBag class.This involves the following topics/concepts:

1. Inheritence
2. Virtual constructors
3. Virtual destructors
4. Virtual member functions
5. Allowing a 'BaseClass' pointer to point to a 'DerivedClass' instance
6. Casting a 'BaseClass' pointer to a 'DerivedClass' type
7. Given:
• BaseClass b, *pb;
• DerivedClass d, *pd;
• Something like the following will appear in your derived class
• virtual bool operator==(const BaseClass & RHS)
• {   if ( data == ((DerivedClass*)&RHS) -> data )
• which goes along with something like:
•  virtual bool operator==( BaseClass &RHS ) = 0;
•  which would appear in  class Node
