谭浩强c++课后习题源码解析，附个人的解题方法(Hao Qiang c++ After exercise-source analysis, with individual problem-solving methods)

将TCHAR类型转换成CString类型，VC++精选编程学习源码，很好的参考资料。(The TCHAR CString type, VC++ select learning programming source code, a good reference.)

　　　实现以下的无损数据压缩方法 　　　LZ78和LZW算法； 给定若干个输入的字符串流，应用所编写的算法实现压缩，计算压缩比，然后再将压缩的码流进行解码，同输入的字符串流进行比较，判断输入输出码流是否一致。(Achieve the following lossless LZ78 and LZW data compression algorithm certain algorithms to a given input string stream to achieve compression applications written to calculate the compression ratio, and then decoding the compressed code stream, with the stream input string , and determines the input and output streams are the same.)

利用系统热键可以方便用户的操作，比如经常使用的Alt + Tab可以快速切换窗口；Crtl + Alt + Delete键可以调出Windows任务管理器或重启机器；oicq软件也会注册系统热键方便用户的操作，等等。本程序就注册一个系统热键Alt + Z，在应用程序执行的任何时候只要按下该热键就会弹出一个消息对话框。 (system hotkeys can use user-friendly operation, For example, the regular use of the Alt-Tab window can quickly switch; Crtl-Alt-Delete keys could be released Windows Task Manager or the reopening of machinery; oicq software registration system hotkeys will be user-friendly operation, and so on. The procedure for registering a system hotkeys Alt Z, Application procedures for the implementation of any time by pressing the hotkey will pop up a message box.)

定义一个基类MyGraph，要求有一个纯虚函数double Area()=0。从基类派生一个圆类Circle和矩形类Rectangle，再由Rectangle类派生出Square类，分别给出Area()实现。 重载“>>”，实现对图形信息的输入。在主函数中计算三种形状的面积，并显示输出。 (Define a base class MyGraph, requires a pure virtual function double Area () = 0. Derive a circle and a rectangle class Rectangle Circle class from the base class, and then by Square Rectangle class derived class, are given Area () implementation. Reload " > > " to achieve the input of graphical information. Calculate the shape of the three main functions in the area, and display output.)
