C++ VS C# Key Points

本文详细阐述了C++和C#中实现多态性的方法,包括在基类中使用virtual关键字,在派生类中使用override关键字。同时对比了两种语言在成员变量初始化方面的差异,C++需要初始化器,而C#允许直接初始化。

There is a pdf talking about this in detail (in my skydrive). Here just list some key points:

1. To enable polymophyism, we need:
    a. Add virtual in Base class functions. Yes, it's same as c++ does.
    b. Add override in intented child class. It's a must in C# while in C++ no need.

2. For C++, it needs initializer to initialize member variables; while for C#, it needn't as it allows direct initialization in coding (Fields can be initialized during declaration or afterward,).
