Console display board(improved)

A. Thired Edition
These classes are all base classes for console displays and on this edition I finished a board 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
