第二个规则: 从私有基类继承而来的成员都成为了派生类的私有成员,即使它们在基类中是保护或公有成员。私有继承的含义:私有继承意味着 "用...来实现"。如果使类D私有继承于类B,这样做是因为你想利用类B中已经存在的某些代码,而不是因为类型B的对象和类型D的对象之间有什么概念上的关系。因而,私有继承纯粹是一种...
public inheritance makes public members of the base class public in the derived class, and the protected members of the base class remain protected in the derived class. protected inheritance makes the public and protected members of the base class protected in the derived class. private inheritance...

C++用三个关键词来表示访问范围:public, protected, private。 public和private作用就是实现封装。类外的代码可以访问public成员而不能访问private成员;private成员只能由类成员访问。 protected的作用则是实现继承。protected成员可以被派生类(也叫子类)对象访问,不能被用户代码类外的代码访问。

对于公有继承:基类的 protected 和 public 成员都是可见的。并且,使用公有继承,基类的公有成员将变为派生类的公有成员,基类的保护成员将变成派生类的保护成员,基类的私有成员将变为派生类的私有成员。 对于保护继承:使用保护继承时,基类的公有成员和保护成员都会变成派生类的保护成员。这就是保护继承和公有继承的...
