C++中虚函数与虚析构函数作用的讨论

Discussion about Virtual Function and Virtual Destructor in C++

给出了C ++中用于实现多态的一种重要的机制———虚函数与虚析构函数的作用及用法 ,C ++中多态的分类、特点及实现方式。

This paper introduces an important mechanism to implement polymorphism in C++—— the application and usage of virtual function and virtual destructor, it also introduces the classification,properities and ways of implementation of polymorphism in C++, it lays much emphasis on describing the application and usage of virtual destructor.
