数据结构：抽象数据类型的介绍；讲述如何构造函数和如何实现；(Data structure: the introduction of abstract data types on how to structure function and how to achieve )

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)

开括号和比括号的匹配，数据结构内容，很不错(More than brackets and brackets to open the match, the contents of data 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.)

本代码是通过C语言来实现贪心算法求着色问题,包括具体问题和实现代码(This code is the C language to implement the greedy algorithm for the coloring problem, including specific issues and the implementation code)

包括链表的各项操作，添加、删除、修改等。还包括单项连标和双向链表。(including the operation, add, delete, revise. Also including individual targets and even two-way linked list.)

校园导航系统 1） 校园景点介：绍介相关景点的有关详细信息。 2） 最佳路线查询：查询校园中任意两点之间所有路线，并提供两点间最短的简单路径。 3） 关节点查询：提供校园图的关节点查询。 4） 多景点最佳路线查询：提供多个景点的最佳线路查询，即求途径这个景点的最佳路径。 (Campus Navigation System 1) campus attractions Introduction: Shao Jie-related attractions for more information. 2) The best route query: Query on campus all the routes between any two points, and provides a simple shortest path between two points. 3) joint points: the key points to provide the campus map queries. 4) The best route queries more attractions: multiple sites to provide the best route queries, that is seeking ways to this spot the best path.)

说明：  读取股票数据文件,C++源程序，非常好用。是学生做毕业设计的源料(Read the Stock Data File)
