Modern C++ Design Generic Programming and Design Patterns Applied

实现基于二叉树表示的算术表达式Expression的操作。 （3） 程序执行的命令为： 1）输入表达式； 2）输出前缀表达式； 3）输出中缀表达式；4）常量合并后表达式；5）赋值后的表达式；6）表达式的复合。 -Binary tree based on the arithmetic expression Expression express operation. (3) procedures for the implementation of the command as follows: 1) input expression 2) expression of the output prefix 3) the output is made up of expressions 4) constant expression after the merger 5) after the assignment expression 6) expression type of composite.

1.程序能够从题库随机选择20道混合运算，用户输入答案，程序检查答案是否正确，每道题正确计5分，测试结束后给出总分；2.题库文件自动生成，程序提供三种练习功能选择：百以内整数算式、带括号算式、真分数算式练习；3.程序进行多轮测试，并用柱状图显示多轮测试分数；6.程序记录用户答题结果，当程序退出再启动的时候，可为用户显示最后一次测试的结果，并询问用户可否进行新一轮的测试；测试有计时功能，测试时动态显示用户开始答题后的消耗时间；7.程序人机交互界面是GUI界面

嵌入式WINCE实现画图特殊效果,用EVC开发实现的例子-Embedded WINCE realize drawing special effects, and realize the development of examples of EVC

windows下，USB程序，VC编译运行通过，实现了USB的一些基本功能-windows, under, USB program, VC compiled to run through to achieve some of the basic features of the USB

这个是用分段法求解线形方程组的算法，可以看一下，有帮助的-this section is used method of linear equations algorithm can look at, help

这是一个人机对战游戏，字符界面，入门级别。每次可取1-4根，取最后一根者为输。本程序的算法很简单，但谁都是从基础起步的。 -This is a human-computer game players, a character interface, the entry-level. Each root desirable 1-4, the last one who admitted to lose. This procedure is very simple algorithm, but who are starting from the foundation.

全局函数使用起来很方便，不需要很多的包含头文件，在每种类中都可以用。可是，他的实现上也要注意一些细节，本实例就是出于这一目的，给出简单事例，教初学者如何使用全局类的方法。 希望对大家有所帮助。 -It is very convenient by using global function because it needn t include many head files and can be used in almost every class.But when you use it you should pay attention on some details,and the example given here will introduce beginners some methods on how to use global class.I hope it will be usefull for you
