C++ virtual inheritance ZZ 虚继承是面向对象编程中的一种技术,是指一个指定的基类,在继承体系结构中,将其成员数据实例共享给也从这个基类型直接或间接派生的其它类。 举例来说:假如类A和类B各自从类X派生(非虚继承且假设类X包含一些数据成员),且类C同时多继承自类A和B,那么C的对象就会拥有两套X的实例数据(...

Multiple inheritance in C++ is a powerful, but tricky tool, that often leads to problems if not used carefully. This article will teach you how to use virtual inheritance to solve some of these common problems programmers run into. If you're not familiar with multiple inheritance, check out ...

C++语言的解决方案是,提供另一种可替代按“引用组合”的继承机制虚拟继承(virtual inheritance )在虚拟继承下只有一个共享的基类子对象被继承而无论该基类在派生层次 中出现多少次共享的基类子对象被称为虚拟基类。 通过用关键字virtual 修政一个基类的声明可以将它指定为被虚拟派生。例如,下列声明使得ZooAnimal 成为Be...

Virtual是C++ OO（面向对象机制）机制中很重要的一个关键字。虚函数就是因为成员函数加了关键字virtual，可见它的重要性。只要是学过C++的人都知道在类Base中加了Virtual关键字的函数就是虚拟函数（例如函数print），于是在Base的派生类Derived中就可以通过重写虚拟函数来实现对基类虚拟函数的覆盖。当基类...
