The concept of polymorphism Polymorphism (implemented in C++with virtual functions)is the third essential feature of an object oriented programming language, after data abstraction and inheritance. Polymorphism allows improved code organization and readability as well as the creation of extensible programs that can be “grown”not only during the original creation of the project,but also when new features are desired. 2017年4月26日星期 第12章多态性与虚函数 0画2时14分39秒 BACKHOME2017年4月26日星期 三12时14分39秒 第12章 多态性与虚函数 9 Polymorphism (implemented in C++ with virtual functions) is the third essential feature of an object oriented programming language, after data abstraction and inheritance.
