A practical example of multiple inheritance in C++

It is not the purpose of this paper to formally present the syntax and semantics of multiple inheritance in C++. The reader is referred to Stroustrup's AT&T report, Multiple Inheritance for C++ for such details. To learn more about the general issues associated with multiple inheritance, we recommend the paper by Bertrand Meyer in the Journal of Object-Oriented Programming, Harnessing Multiple Inheritance. Finally, Section 9 of our forthcoming book, The C++ Workbook, by Wiener and Pinson, Addison-Wesley, October, 1989, presents the mechanics of multiple inheritance in C++ in great detail with many examples.
