Multiple Inheritance is a feature of C++ where a class can inherit from more than one classes. The constructors of inherited classes are called in the same order in which they are inherited. For example, in the following program, B’s constructor is called before A’s constructor. 1#include...
Example 3: Hierarchical Inheritance in C++ Programming // C++ program to demonstrate hierarchical inheritance#include<iostream>usingnamespacestd;// base classclassAnimal{public:voidinfo(){cout<<"I am an animal."<<endl; } };// derived class 1classDog:publicAnimal {public:voidbark(){cout<<"I ...
When the inheritance is public, the derived class and every body else can access the public members of base class through derived class because these members now become the public members of derived class. So, it for you to decide if you want this kind of visibility or not? When the inher...

本文主要介绍了gcc编译器中multiple 和 virtual inheritance中的对象内存布局。虽然C++程序员不需要关心编译器的内部细节,但多重继承(特别是虚拟继承)在C++代码实现中有不同的结果(特别是用pointers to pointers 来实现downcasting pointers,constructors for virtual bases的调用顺序)。如果你了解多重继承和虚拟继承,你就...
It might seem that virtually inheriting CObject would solve the problem of function ambiguity, but that is not the case. Because there is no member data in CObject, you do not need virtual inheritance to prevent multiple copies of a base class member data. In the first example that was ...
In the above one, the methods in the classes C and D are reused in E. The same C and D can also be "reused" by any other class by extending them.[Assume multiple inheritance is allowed]. Consider the below code interface C{ void funC(); } interface D{ void funD(); } class ...
