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。
C++ 中的 public、private 和 protected 继承有什么区别? 回答 C++ Primer Plus 上有个表格很详细, 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。
🍀 只有public和package-private(没有修饰符)可以修饰顶级类(Top-level Class)【顶级类可以有多个,但被 public 修饰的顶级类只能有一个】 publicclassPerson{publicclassFahter{classSon{protectedclassGrandson{privateclassDog{ } } } } } 上面代码中的 Person 就是顶级类,Person 类(顶级类)只能被 public 修...
Second, when a derived class inherits from a base class, the access specifiers may change depending on the method of inheritance. There are three different ways for classes to inherit from other classes: public, private, and protected.
protected: voidPDump(void); private: voidPRDump(void); }; classClassD1 :privateClassDemo { public: ClassD1(void){} ~ClassD1(void){} voidDump(void); virtualvoidVDump(void); }; classClassD2 :publicClassDemo { public: ClassD2(void){} ...
Explain the private, protected and public inheritance. Private Inheritance :All the public and protected members in base become private. Protected Inheritance :All the public and protected members in base class become protected. Public Inheritance :In case of public inheritance, public remains public ...
