Great course to help you get start with C++. Give a lot of details about class. It is good enough thinking that it is a online free course.

Challenging but highly recommended if you really want to learn something serious about C++.

From the lesson

多态与虚函数

多态是指同一名字的事物可以完成不同的功能,例如有几个相似而不完全相同的对象,有时人们要求在向它们发出同一个消息时,它们的反应各不相同,分别执行不同的操作。在C++中,所谓多态性是指由继承而产生的相关的不同的类,其对象对同一消息会作出不同的响应。多态性是面向对象程序设计的一个重要特征,能有效增加程序的灵活性。
