Console Rack

A. Fifth Edition
These classes are all base classes for console displays and on this edition I finished a simple CRack, 
CBackGround class.
B.The problem
How to display in console without using iostream class?
C.The idea of program
 
These classes are for our comp354 project which is going to make a little game like cross word.
D.The major functions
E.Further improvement
