A class can contain not just one but several different base classes. In this case the class is derived from multiple base classes in a process known as multiple inheritance. 䊐 The Multiply-Derived Class MotorHome This

The order of the constructor calls is important. When you inherit, you know all about the base class and can access any public, protected, or internal members of the base class. This means that you must be able to assume that all the members of the base class are valid[r]
