求单词个数的三种算法分析 用户任意输入一个字符串 ，求该字符串中包含的单词个数 ，其 中单词以空格分隔。这道题目难度合适，不用理解复杂的概念，纯粹的考察学生解决问题的能力，而且题目看似简单，学 生很有信心能够解决这个问题。每年讲解程序语言基础课或者程序设计高级时 ，都拿这道题目让学生做练习 ，但是学生做 的情况并不乐观 ，因此有必要总结一下 3 种经典解法 ，让初学者也能够体会到程序和算法的乐趣 ，让学生爱上学习。(Find the number of words any of the three algorithms analyze user inputs a string, find the number of words contained in a string, in which words separated by spaces. This question is difficult to project the right, do not understand the complex concepts, students study the pure problem-solving skills, and the subject appears to be simple, the students are confident to solve this problem. Explain each programming language basic course or advanced programming, they all head to take the problem asks students to do exercises, but students do not optimistic, it is necessary to summarize the three kinds of classical solution, so that beginners can understand the procedures and algorithms fun for students to love learning.)

MDAC（Microsoft Data Access Components）是微软数据库访问组件，Netpise和许多利用数据库的软件都需要操作系统安装MDAC。很多用户的操作系统中已经存在了MDAC，有些是操作系统内置的、有些是其它应用程序安装的。(MDAC (Microsoft Data Access Components) is a Microsoft database access components, Netpise and many need to use the database software operating system to install MDAC. Many users of the operating system already exists in the MDAC, some built-in operating system, some other applications installed.)

学习的时候，试着写的，有待优化，适合初学者

VC++利用Hook钩子实现的阴影菜单，不要误认为是Winodws系统自带的阴影菜单，仔细看你就会发现两者是不一样的，一样令人羡慕不已，尤其是使用钩子实现，相信对VC++编程者来说，有空的时候还是要看一下哦！虽然大家对这种效果已经司空见惯了，但实现起来没有想像的那么简单，因此具有参考价值。(VC++ to use the realization of the shadow of hook Hook menu, do not mistakenly think it is the shadow of Winodws own menu system, look carefully and you will find they are not the same, as is envy, especially the use of hooks to achieve, I believe VC++ programmers, the time or the time to look at Oh! Although there have been commonplace this effect, but not as to achieve the so simple, it has a reference value.)
