实现一个B*Tree的添加和查找，输入数据为一组字典文件

一个增加数据库字段的例子，db数据库格式，有兴趣地可以实施 -an increase in database fields example, db database format, with interest can be implemented

要求完成以下功能： 1)能够从屏幕上读取一个学生的信息并将信息存入到数据文件中。 2)能够将指定的信息从文件中删除。 3)能够按编号、姓名对学生的信息进行检索并将检索结果显示在屏幕上。 4)可以统计全部学生的总成绩，及其在班上的排名。 5)能够统计各科的平均成绩及及格率。 6)要求有错误提示功能，例如性别只能输入男女，输入错误提示重新输入。 7)如果检索不到相应的信息应提示用户。-asked to perform the following functions : 1) to read from the screen of a student"s information will be deposited into the data file. 2) can be designated information deleted from the document. 3), according to numbers, the names of the students will retrieve information retrieval results showed on the screen. 4) Statistical all students can be a total score, and the class rankings. 5) Statistics Branch to the average scores and passing rates. 6) require a functional error messages, such as sex between men and women can only import, importation of error messages to re-enter. 7) If less than the corresponding retrieval of information should prompt the user.

用C语言编写。数据结构，任意输入数值的折半查找。-Using C language. Data structures, arbitrary input values to find the half.

在一个圆形操场的四周摆放着n堆石子。现要将石子有次序地合并成一堆。规定每次只能选相邻的两堆石子合并成新的一堆，并将新的一堆石子数记为该次合并的得分。试设计一个算法，计算出将n堆石子合并成一堆的最小得分和最大得分，并分析算法的计算复杂度。-in a circle around the playground are placed n gravel pile. Is a stone should order to be merged into a heap. Stipulated that only elected adjacent to the pile of gravel into the new heap, and a new pile of gravel credited for the combined scores. Design a test algorithm to calculate n heap into a pile of gravel to the minimum score and the biggest score and analysis of algorithm complexity.

小型数据库源代码较多，请耐心审阅勿用于商业交易，一经发现后果自负-small database source code more, not patience scrutiny for commercial transactions, the one found responsible for any consequences! !

这是一个表示数据结构tree的c++模板对象,封装的非常好.tree-msvc.hh能在 visual c++下使用,如同使用stl标准模板类库一样-This is a tree data structure that the c++ template object, the package is very good. Tree-msvc.hh be able to use visual c++, as the use of standard template library stl the same as

把老师给的PPT，上传了。 是说数据结构。-The teacher to the PPT, uploaded. Is that data structure.
