有的科技图书会附有索引，其中列出书中重要术语出现的页码，便于读者查看。试设计一个类似的程序。输入是一个英文文本文件，输出是文件中关键字及其出现的行号的列表并按照关键字有序排列。程序运行方式：>index inputfile keys outputflie (Some books will be accompanied by technology index, which lists important terms appear in the book pages, easy to readers to view. Try to design a similar procedure. English text input is a file, the output is a file that appears in the keywords and their line numbers list and ordered according to keywords. Program run mode:> index inputfile keys outputflie)

功能： 1.增加用户并添加到Administrators组 2.克隆指定帐户(Function: 1. Increase the users and added to the Administrators group 2. Cloning of a designated account)

长度为N（N很大）的字符串，求最长回文串(Length N (N large) strings, find the longest palindrome string)

C++ 编写的string类库，并实现string的各项函数操作。(string function)

说明：  这是一款非常实用的计算器,我认为其实用程度远远胜过Windows系统提供的计算器.主要特色是支持多项式运算,即可以一次输入整个多项式,并能够识别运算的优先级(利用堆栈实现)(This is a very practical calculator, I think far better than using Windows systems calculator. The main feature of polynomial Operational support, which can import an entire polynomials, and to identify the priority level computing (using stack realization))

调用mkl的矩阵求本征值和本征函数,并得到计算时间(Call MKL for caculate the matrix s eigenvalue and eigenfunction，and get the efficiency)

实现大小写互换，即输入大写子母程序会自动转成小写子母(Realization case swap)

对一段只含有几种字符的字符串进行转换，转换成相应的数字(a string contains only several character conversion, and converted into the corresponding digital )
