One, polymorphic
C + + polymorphism is implemented through inheritance and dynamic binding. Inheritance is the inheritance and sharing of code or function, which is external, formal and easy to understand from the point of view of language. Dynamic
C + + Object-oriented language A major difficulty is inheritance, but it has to be mastered. Simple inheritance is easy to understand, but when it comes to multiple inheritance, design to virtual function inheritance, especially when it comes to
Single inheritance is a general single inheritance, when a subclass has only one direct parent class that is called the inheritance relationship as a single inheritance. This kind of relationship is relatively simple and one-on relationship:Multiple

Today I saw a very good article on the internet, which is about the C + + class inheriting the memory layout. After looking at the benefit of a lot, now turned in my own blog inside, as a later review of the use.

C + + class because of the existence of inheritance is more complex than the C-era struct, especially when the virtual function, as well as the multi-inheritance, and so on, so that its memory layout becomes unrecognizable. I can not grasp the truth,
One: the memory model under C + + single inheritance:A), simplest of a single inherited memory model: No virtual function member in base classes and derived classes:#include classbase{ Public: Base (Char_x =' /'): m_x (_x) {}~Base () {}Private:

The definition of virtual inheritance and virtual base classes is very simple, but in C ++, virtual inheritance exists as a relatively uncommon but absolutely necessary component, in addition, its
