C++中，对链表的增删改查的基本使用，值得学习(C++, on the list of CRUD basic use, it is worth learning)

数据结构中图的遍历Data structure traversal of center(Data structure traversal of center)

设计、编写和调试面向对象C++程序，实现任意两个同类数据比大小 的通用函数（模板），涵盖普通数值型数据之间的比较、两个字符串之间的比较 （按字典序）、两个复数之间的比较（按模大小）等，并通过主函数加以调用和 测试。(Design, writing and debugging of object-oriented C++ procedures to achieve similar data than the size of any two generic functions (template), covering general comparison between numerical data, the comparison between the two strings (lexicographically), two Comparison between complex numbers (modulo the size), and through the main function to be invoked and tested.)

　广度优先搜索及深度优先搜索，用C语言实现，比较使用(Breadth-first search and depth first search, using C language, compared with)

说明：  可以实现判断二叉树是否为完全二叉树、判断两棵二叉树是否镜像对称、求一棵二叉树的一个最长枝等功能(Can determine whether the binary tree is complete binary tree to determine whether two binary mirror symmetry, one of the longest seeking a binary tree branches and other functions)

克鲁斯卡尔算法思想.cpp int seekedge(EDGE * (&a), int n) void bubble(EDGE * (&a), int size) void searchandjoin(EDGE * (&a1), int k) // a1是图边集头指针，a2是最小生成树边集的头指针，k为所要删的边 void storepicture(EDGE * (&a), int n, VERTEX *b, int m) (Thinking of Kruskal algorithm. Cpp int seekedge (EDGE* (& a), int n) void bubble (EDGE* (& a), int size) void searchandjoin (EDGE* (& a1), int k) // a1 edge set is the first pointer map, a2 is the minimum spanning tree of the first indicators margination, k for the edges to be deleted void storepicture (EDGE* (& a), int n, VERTEX* b, int m) )

大二时做的一个数据结构的课程设计，用2-3树实现的图书馆管理系统，只是控制台程序，没有很好的图形界面。包括管理员、读者。管理员功能有：采编入库、查看图书、查看读者、删除读者。读者功能有：借书、还书、预约、查找等等。。功能全面。包括注册账号，登录需要账号密码。(Sophomore to do a data structure of the curriculum design, with 2-3 tree implementation of library management system, but the console program, not a good graphical interface. Including administrators, readers. Administrator functions include: editing storage, check books, check readers, delete readers. Reader functions: library, book, booking, search and so on. . Full-featured. Including the registration account, login account password required. )

说明：  从最后一个非叶子结点开始从后往前进行调整，保证了根下的所有子树都是最大堆，最后对根进行调整，使整棵二叉树为最大堆，保证了根结点为整棵数的最大值点，完成了建堆的过程，再将根结点跟最后一个结点进行交换，如此反复操作，则堆排序就完成了，其中堆排序的过程采用了满二叉树的概念。(From the final of a non-leaf node after the move began to be adjusted to ensure that the root of all sub-tree are the biggest pile, and finally adjusted to the root, so that the largest heap binary tree整棵to ensure that the root node for整棵the maximum number of points, completed the process of building reactors, and then the last root node with a node to be exchanged, and so repeated the operation, then HEAPSORT completed, of which the process of HEAPSORT a full binary tree concept.)

冒泡优化： 如果一个序列是int n[]={1,2,3,4,5,6,7,8,9} , 用正常的冒泡排序需要排8次才行，优化之后1次就好，也就是说序列越接近于正常序列，改进之后的冒泡排序的次数就越少，这样会给一个冒泡排序算法带了很大的效率。 思想：添加一个boolean变量用来判断冒泡是否是已经排好了顺序，如果boolean的值为false，说明是已经排好了，如果boolean的值true，说明没有排好，继续排。(If a sequence is int n [] = {, 1,2,3,4,5,6,7,8,9} need to row 8 times the job after optimization times like normal bubble sort, but alsomeans that the sequence is more close to the normal sequence, improved bubble sort, the less the number, which would give a bubble sort algorithm with a great deal of efficiency. Idea: add a boolean variable used to determine the bubble whether it is already lined up the order, if the boolean is false, indicating already lined up, if the boolean value of true, did not line up, continue to row.)

本系统采用C语言编写，利用邻接链表实现最短路径问题，关键路径问题等(The system uses the C language, using adjacency list realize the shortest path problem, critical path issues)
