多种方法实现栅格数据计算NDVI，包括逐个像素处理、栅格计算器计算。(A variety of methods to calculate raster NDVI, including by-pixel processing, raster calculator.)

读取一个文本文件（英文，ASCII编码），对出现的单词次数进行统计，并按照出现次数从低到高排序，输出到一个文本文件中（每行一个单词信息，格式：单词 出现次数）。采用二叉树结构存储，中序遍历，快速排序。(Reads a text file (English, ASCII encoding), the number of occurrences of the word statistics, and in accordance with the number of occurrences of the sort low to high, output to a text file (one word per line message format: word occurrences). Binary tree structure stored in preorder, quick sort.)

输入一个矩阵，可以求得该矩阵的逆矩阵，内附解释说明(Enter a matrix, you can obtain the inverse matrix, containing an explanation)

说明：  使用vc++6.0开发的一个小例子，保护视力程序，界面简单，主要是实现将应用放到系统托盘中。(Use vc++ 6.0 to develop a small example of procedures to protect their eyesight, the interface simple, the main factor will be applied to achieve on the system tray.)

在 Visual C++中操作Excel,对开发数据库管理系统很有意义(Operation Excel in Visual c + +, is very meaningful to the development of database management system)

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 )

说明：  下面是一个结构体声明： struct box { char maker[40] float height float width float length float volume } a. 编写一个函数，按值传递box结构，并显示每个成员的值 b. 编写一个函数，传递box结构的地址，并将volume成员设置为其他三维长度的成绩。 c. 编写一个使用这两个函数的简单程序 (Here is a structure declaration: struct box {char maker [40] float height float width float length float volume } a. Write a function that is passed by value box structure, and shows the value of each member b . to write a function, passing the address box structure and volume settings for the other three members of the length of the results. c. use these functions to write a simple program)

说明：  a)需求分析： 任务：建立南京主要公交线路图。 要求：输入任意两地点，给出最佳的乘车线路和转车地点。 b)概要设计： 本程序所使用的数据结构是树和线性表，所使用的算法主要有堆排序、赫夫曼算法。 (a) Requirements Analysis : Mandate : the establishment of the Nanjing main transit route map.
