"Effective C + +"

Article 34: Differentiating between interface inheritance and implementation inheritance

Public inheritance is made up of two parts

Function Interface Inheritance

function Implementation Inheritance

Three types of inheritance that may be faced

Derived class only interfaces that inherit member functions

Derived class inherits the interface and implementation of the function, but also wants to overwrite the implementation that they inherit

Derived class concurrently inherits the interface and implementation of the function, but does not allow the overwrite of anything

Summarize:

Interface inheritance differs from implementation inheritance. under public inheritance,derived classes always inherits the interface of base class .

The Pure virtual function specifies only interface inheritance.

The simple impure virtual function Specifies interface inheritance and default implementation inheritance.

The non-virtual function specifies interface inheritance and mandatory implementation inheritance.
