Quick search on Google for "c++ polymorphism" comes up with a few reasonable examples. You know you've hit it when you encounter Base Classes and the 'virtual' keyword (Chapter 10, section 2 in Safe C++ Design Principles). I personally don't like the word "polymorphism". People get confused and start spouting off incorrect nonsense. I have to run a Google search to remember what it means - I just use it and don't really care what people call it. The phrase "base classes" carries more meaning for me because you derive classes from a base class and pass the base class around. Polymorphism is a fancy word and I don't like fancy words because my brain doesn't do fancy words. -- Thomas Hruska CubicleSoft President Ph: 517-803-4197 *NEW* VerifyMyPC 2.3 Change tracking and management tool.
