C++多态性的实现过程

Implementation of C++polymorphism

多态性特征是C++中最为重要的一个特征,熟练使用多态是学好C++的关键,而理解多态的实现机制及实现过程则是熟练使用多态的关键。文章在分析多态性基本属性的基础上,结合具体程序实例重点分析了动态多态的实现机制,并结合虚函数和联编原理分析了动态多态的实现过程。

Polymorphism is the most important feature in C++.Skillful use of polymorphism is the key to learn C++well,while understanding the implementation mechanism and process of polymorphism is the key to use polymorphism skillfully.Based on the analysis of the basic attributes of polymorphism,this paper focuses on the implementation mechanism of dynamic polymorphism with specific program examples,and analyzes the implementation process of dynamic polymorphism with virtual function and binding principle.
