本章将介绍C++编程语言的最基本的元素，以及C++的指针、引用和作用域。在第3章和第4章，将介绍C++的类和面向对象编程。在你使用微软基础类库(Microsoft Foundation Class Library，MFC)进行Windows编程时，你需要所有这些知识。 C++是一种复杂的语言，它的许多元素非常抽象。它也是一个庞大的语言，为专业编程而设计。本书的重点是使用Visual C++语言来利用MFC编写Windows程序，因此没有深入地讨论C++语言。 MFC是构造于原始C++之上的应用程序框架，它提供了一个Windows应用程序工作的基础，一个可以向内添入自己代码的框架。这个框架提供了绝大多数Windows特征――菜单、工具栏、对话框、控件和滚动条。它也提供使开发者能相对容易的将数据写入文件、打印数据等机制。这个框架的部件是C++的类，这些类表示了应用程序的组件，例如应用程序的主窗口、它的对话框、字符串、如矩形和点的图像对象，甚至应用程序本身。因此，为了使用Visual C++编写Windows程序，你需要知道足够的C++知识来利用MFC。 -C programming language, the most basic elements, and C pointers, use and scope. In Chapter 3 and Chapter 4, will introduce the class C and object-oriented programming. Your use of Microsoft Foundation Class Library (Microsoft Foundation Class Library, MFC) for Windows programming, you need all knowledge. C is a complex language, and many of its elements is very abstract. It is a huge language, as a professional programming and design. The book focuses on the use of language Visual C MFC prepared to use Win

定义一个车(vehicle)基类，有Run、Stop等成员函数，由此派生出自行车(bicycle)类、汽车(motorcar)类，从bicycle和motorcar派生出摩托车(motorcycle)类，它们都有Run、Stop等成员函数。在main()函数中定义vehicle、bicycle、motorcar、motorcycle的对象，调用其Run()、Stop()函数，观察其执行情况。再分别用vehicle类型的指针来调用这几个对象的成员函数，看看能否成功；把Run、Stop定义为虚函数，再试试看。-The definition of a car (vehicle) base class, with Run, Stop and other member functions, thus derived a bike (bicycle), automobiles (motorcar) class, derived from the bicycle and motorcar motorcycle (motorcycle) class, they all Run , Stop and other member functions. In the main () function is defined in the vehicle, bicycle, motorcar, motorcycle object, call its Run (), Stop () function is to observe its implementation. Each with a pointer with the vehicle type to call the member functions of these objects to see if successful the Run, Stop is defined as virtual functions, try again.
