一、 地理数据文件应用 对由点、线、面构成的地理数据文件进行打开、读取、关闭操作。 要求： 1、在C++环境下，通过程序设计实现文本格式数据文件的操作； 2、在打开数据文件后，生成点、线、面三个链表，分别用于记录三种类型的数据。 3、数据文件结构说明 (Geographic data file applications by point, line, surface consisting of geographic data file open, read, and close operations. Requirements: in C++ environment, through the program design text format data file operations 2, open the data file, generate points, lines, surfaces three linked list, respectively, for the record three types of data. 3, a data file structure)

设有一头指针为L的带有表头结点的非循环双向链表，其每个结点中除有prev（前驱指针），data（数据）和next（后继指针）域外，还有一个访问频度域freq。在链表被起用前，其值均初始化为零。每当在链表中进行一次Locate(L,x)运算时，令元素值为x的结点中freq域的值增1，并使此链表中结点保持按访问频度非增（递减）的顺序排列，同时最近访问的结点排在频度相同的结点的最后，以便使频繁访问的结点总是靠近表头。试编写符合上述要求的Locate(L,x)运算的算法，该运算为函数过程，返回找到结点的地址，类型为指针型。(Has a head pointer is non-circular doubly linked list L with a header node, each node in addition to prev (precursor pointer), data (data) and next (successor pointers) outside, there is an access frequency degree domain freq. Before the list was hired, their values are initialized to zero. Whenever carried out in the list once Locate (L, x) when the operation, so that the element node x is the value in freq domain by one, and keep this list in the node-access frequency of non-increasing (decreasing) the order, while a recent visit to the nodes in the same row of the frequency of the last node, so that the nodes are frequently accessed tables are always near the head. Locate (L, x) algorithm is prepared in accordance with the above requirements of the test operation, the operation as a function of the process, return to find the address of the node of type pointer.)

代码注重B树插入、删除的算法逻辑，适用于 学习者研究B树实现的核心思想。代码中无庞杂的无关操作(focus on B-tree code insertion, deletion algorithm logic applies to B-tree research learners to achieve the core idea. The code has nothing to do with the complex operation )

说明：  分别用堆栈和数组的方法实现任何进制的数制转换(Arrays were used to stack and method of implementation of any binary number system conversion )

这是acm高手楼天城的比赛代码，很有用哦，对于提高算法非常有用(This is a master of building Tiancheng acm game code, very useful oh, for improving the algorithm)

B-树的创建、插入、删除等一系列操作！(B-tree creation, insert, delete a series of manipulations!)
