The process of inheriting base classes virtual so that only a single copy of its member will appear in the derived class is called virtual inheritance. The corresponding shared base class is called a virtual base class. In the above example, using virtual inheritance, the duplication of members...
class transmitter: public virtual storable { public: void read(); ... } class receiver: public virtual storable { public: void read(); ... } When we use virtual inheritance, we are guaranteed to get only a single instance of the common base class. In other words, the radio class wi...
Classes in OOP also define the objects to which the program relates. If a function is defined with a reference to a base class as a parameter, one can pass an object of a derived class to it as an argument. The chapter covers the principal ideas involved in using inheritance for native...

http://stackoverflow.com/questions/4487914/which-function-to-call-delegate-to-a-sister-class Quote: What is happening behind the scene. The simple explanation is that, because inheritance fromBaseis virtual in bothDer1andDer2, there is a single instance of the object in the most derived objec...
The following figure shows how objects are composed using virtual and nonvirtual inheritance. Virtual vs. Nonvirtual Derivation In the figure, accessing any member of class A through nonvirtual base classes causes an ambiguity; the compiler has no information that explains whether to use the subobject...

In an initialization list, the order of initialization shall be following: (1) virtual base classes in depth and left to right order of the inheritance graph, (2) direct base classes in left to right order of inheritance list, (3) non-static data members
