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)

输入N个点的坐标，判断这N个点能否构成一个凸多边形。(Enter the coordinates of N points, to determine whether the N points form a convex polygon.)

单链表程序 可执行单链表的基本功能 创建 删除 查找 存取 等等(Basic functions to create a single linked list program executable single linked list delete find access)

双链表的定义和插入算法，双链表的定义，删除，插入和查找算法(Doubly linked list of definitions and insertion algorithm, the definition of double-linked list, delete, insert, and search algorithm)

该代码实现了深拷贝的问题，对于深拷贝进行了一系列的介绍，并且显示其与浅拷贝的区别。(A deep copy of the code issues a series of deep copy for presentation, and shows the difference between a shallow copy.)

POJ 字符串的插入 可以将一定长度的字符串插入之前给出的字符串之中(POJ string can be inserted into a length of string into a string before being given)

这是BFS算法的实现。用C语言实现的。好好学习吧。(This is achieved BFS algorithm. Implemented using C language. Learn it.)

找出数组A中最长的递增序列的长度，使用动态规划算法，复杂度为O(N*N)。(Find the longest increasing sequence)

这是一个实现找出欧拉路径的的算法，比较完美的解决了欧拉算法(This is an implementation of the algorithm to find Euler path, the more perfect solution to the Euler algorithm)

说明：  用从c＋＋写的floyd最短路径算法，可以求邻接矩阵任意两点的最短路径。(from using c++ to write the Floyd shortest path algorithm, can help adjacency matrix arbitrary 2:00 Shortest Path.)
