Virtual Base Classes

This ambiguity can be resolved if the class derived have only one copy of the class base. This can be done by making the base class a virtual class. This keyword makes the two classes share a one copy of their base class . It can be done as follows :

                class base

                 {

                                :

                                :

                 };

class  Aclass : virtual public base

                 {

                                :

                                :

                 };

 

                class  Bclass : virtual public base

                 {

                                :

                                :

                 };

 

                class  derived : public Aclass, public Bclass

                 {

                                :

                                :

                 };

This will resolve the ambiguity included.
