With private inheritance, public and protected member of the base class become private members of the derived class. That means the methods of the base class do not become the public interface of the derived object. However, they can be used inside the member functions of the derived class. ...

In C++ inheritance, we can derive a child class from the base class in different access modes. For example, class Base { ... ... ... }; class Derived : public Base { ... ... ... }; Notice the keyword public in the code class Derived : public Base This means that we have c...

sealed class Singleton { private Singleton() { } public static readonly Singleton TheInstance = new Singleton(); } As in C++, you can use a private constructor to prevent programmers from creating instances of Singleton. To prohibit inheritance, declare your class sealed. (In...

1,先搞清楚private inheritance的行为: (1)如果class之间是私有继承的关系,编译器不会将一个派生类自动转化为基类. (2)由基类继承而来的所有成员,在派生类中都会变成private. 2,私有继承:只有实现部分被继承,接口部分应略去. 因此,如果你让D私有继承B,那么你是想采用class B内的某些程序代码,而不是因为B和D的...
