C++ Interface Class

This C++ code is intended to be a tutorial. It is an extension of the idea presented in Item 42 of Scott Meyer s "Effective C++", 2nd Edition. In his discussion he creates a generic stack class to contain pointers-to-objects. His class is written with a void* based implementation, and a template-based interface. The chief aim of restricting templates to interface classes is to reduce "code bloat", which is the replication of template code for each instantiated type. Bloat increases the overall size of the object code.



In my demo, I extend the interface-class idea to create a generic stack class to contain objects (ie, not just pointers to objects). This demo also provides a nice example of using "placement new" and explicit destruction.
