,也是各种CLI语言之间相互区分的一种体现。 例如,CLI本身并不支持多类继承(multiple class inheritance,简称MCI),而只支持多接口继承和单类继承。 但Eiffel语言在设计其面向CLI的实现时就选择了支持源代码 级的多类继承。这需要一种巧妙、甚至是复杂的设计将源代 码级的多类继承映射为底层CLI的单类继承模型。Eiffel...
美国AT&T贝尔实验室的本贾尼·斯特劳斯特卢普(Bjarne Stroustrup)博士在20世纪80年代初期发明并实现了C++(最初这种语言被称作“C with Classes”)。一开始C++是作为C语言的增强版出现的,从给C语言增加类开始,不断的增加新特性。虚函数(virtual function)、运算符重载(operator overloading)、多重继承(multiple inherit...
一个类可以继承多个基类,用逗号分隔,例如class Rectangle: public Polygon, public Output; class Triangle: public Polygon, public Output; 具体的例子 // multiple inheritance#include<iostream>using namespacestd;classPolygon{protected:intwidth, height; public: Polygon (inta,intb) : width(a), height(b)...
一开始C++是作为C语言的增强版出现的,从给C语言增加类开始,不断的增加新特性,如虚函数(virtual function)、运算符重载(operator overloading)、多重继承(multiple inheritance)、模板(template)、异常(exception)、RTTI、名字空间(name space)逐渐被加入标准。

12 C++允许一个派生类同时继承多个基类,这种行为称为多重继承(multiple inheritance)。 声明多重继承的方法 如果已声明了类A、类B和类C,可以声明多重继承的派生类D: class D: public A, private B, protected C { 类D新增加的成员 } D是多重继承的派生类,它以公用继承方式继承A类,以私有继承方式继承B类...
