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 c…

Sadly, 这节课带过去的笔记本没电了 T^T 导致没有一行 Code, Sorry 笔记如下: Shape * p1; //使用指针创建对象的方法 p = new Circle (2.0); Shape * p2; p = new Rectangle (3.0, 5.0); class Shape { public: ; //Pure virtual function } //Warning: 纯虚函数不能以内敛的形式进行定义,只能在类的外部定义 //如果,抽象基类中没有定义的虚函数,那么,…

NOTE: 1.多重继承比单一继承复杂.它可能导致新的歧义性,以及对virtual继承的需要. 2.virtual 继承会增加大小 速度 初始化(及赋值)复杂度等等成本.如果virtual base class 不带任何数据,将是最具价值的情况. 3.多重继承的确有正当用途.其中一个情节涉及“public 继承某个interface class”和“private 继承某个协助实现的class”的两相组合.…

Memory Layout for Multiple and Virtual Inheritance(By Edsko de Vries, January 2006)Warning. This article is rather technical and assumes a good knowledge of C++ and some assembly language.In this article we explain the object layout implemented by gc…

在C++中,所谓"继承"就是在一个已存在的类的基础上建立一个新的类.已存在的类(例如"马")称为"基类(base class )"或"父类(father class )".新建的类(例如"公马")称为"派生类(derived class )"或"子类(son class )". 以上介绍的是最简单的情况:一个派生类只从一个基类派生,这称为单继承(single inhe…

JavaScript is a class-free, object-oriented language, and as such, it uses prototypal inheritance instead of classical inheritance. This can be puzzling to programmers trained in conventional object-oriented languages like C++ and Java. JavaScript's…

<Item 36> Never redefine an inherited non-virtual function 1.如下代码通过不同指针调用同一个对象的同一个函数会产生不同的行为The reason for this two-faced behavior is that non-virtual functions like B::mf and D::mf are statically bound (see Item 37). That means that because pB is d…
