The C++ language supports the concept of multiple inheritance. This means one class can have multiple base classes. This feature is not available in other languages, such as C# or Java. The designers of these languages didn’t considered the benefits of supporting this feature to worth the effort. And probably one of the reasons is that multiple inheritance may lead to the so-called diamond inheritance problem, when one class derives from two different classes, that in turn derive from the same class. In this article, I will discuss the problem as well as the solution in C++.
