Detailed Description

Demonstrates inheritance, virtual methods and new/delete.

Author:

Markus L. Noga <markus@noga.de>

A StateChanger interface class is introduced. Two subclasses implement different behaviours with virtual methods, adressing display and beeper, respectively.

main() successively generates StateChanger objects. Their virtual methods are are invoked via interface wrappers onOff() and setState(s).
