[edit]
And...errrmm... what's your question again?

Class building is the base class
All other classes are derived from Building

All I'm trying to to is to and print the derived classes with the values assigned in main thru overloaded constructors

private functions in building are rooms, floors, area and heatype

The derived classes ,addition in this example, school also has as members washrooms, classrooms and offices,

The HTML editor does not seem to want to cooperate.

I appreciate any help
