Multiple Inheritance

C++ allows a class to have multiple based classes.

class Car : public Vehicle , public InsuredItem {
 ...
 };

This specifies that Car should have all the members of both the Vehicle and the InsuredItem classes.

Multiple inheritance is tricky and potentially dangerous:

• If both Vehicle and InsuredItem define a member x this can cause problems.

• If both Vehicle and InsuredItem inherited from the same base class, you’d end up with two instances of the base class within each Car.
