基于对象的编程风格 4.1 如何实现一个class 1 前置声明使我们得以进行类指针(class pointer)的定义,或以此class作为数据类型. 2 private members 只能在member function或是class friend内被取用.

派生类的构造函数基类指针,我怎么指向基类的指针?
For a derived class with a constructor that takes a base class pointer, how do I refer to the base class pointer?
如果我有一个对象的指针,转换到它的基类指针对象上,我能通过基类指针调用合适的成员函数。
If I have a pointer to an object cast to one of its base classes, I can call the correct member functions through the abstract base class.
例如,不像一个类转型异常,空指针异常不给出它所需要的内容的任何信息,只有一个空指针。
Unlike, for example, a class-cast exception, a null-pointer exception says nothing about what was expected instead of the null pointer.
Once I've got that, I can now start giving some variable names, sorry not, rephrase that, I can give some attributes, I can give some characteristics to these classes.
还有个指向内存中地址的指针,我还可以命名这个指针,因此cp1和cp2都是,指向它们的指针,一旦我创建了它类,我就可以开始赋予。
