Multiple Inheritance Considered Useful

摘要

The title of this article, "Multiple Inheritance Considered Useful," is a bit of a philosophical statement. I do not claim that I use multiple inheritance in C++ all the time, but on occasion, I do find it quite useful. I know I am not the only person who feels this way, but nevertheless, you find a lot of corporate C++ coding standards and even recommendations by C++ experts that suggest you should avoid multiple inheritance. Furthermore, there are a number of other object-oriented languages, several of them newer than C++, that do not support multiple inheritance.
