You can inherit from one class, so it would seem to make sense to inherit from more than one class at a time. Indeed you can, but whether it makes sense as part of a design is a subject of continuing debate. One thing is generally agreed upon: You shouldn’t try this until you’ve been programming quite a while and understand the language thoroughly. By that time, you’ll probably realize that no matter how much you think you absolutely must use multiple inheritance, you can almost always get away with single inheritance.

Initially, multiple inheritance seems simple enough: You add more classes in the base-class list during inheritance, separated by commas. However, multiple inheritance introduces a number of possibilities for ambiguity, which is why a chapter in Volume 2 is devoted to the subject.
