纯C语言编程的模拟现有图书馆的借阅、续借、归还；图书入库、出库；查询、排序等功能，实现电子图书馆的智慧综合管理。其中查询功能里面嵌套精确查询，排序功能有六种，界面可变色，里面已经附带50多本图书信息包括图书摘要等详细信息。里面还附带详细设计报告和解说PPt。(Pure C language programming simulation existing library borrow, renew, return book storage, a library queries, sorting and other functions, to achieve integrated management of electronic library wisdom. Precisely where the query function inside a nested query, sort function has six, the interface can change color, which has included more than 50 books including books summary information and other details. Which also included detailed design reports and commentary PPt.)

说明：  数据结构课上作业实现了一个多项式乘法的功能有注解(Job class data structure implements a polynomial function of multiplication comments)

拓扑排序 -打印输出计算机本科专业4年每学期的课表(Topological sort - computer printout of undergraduate curriculum of each semester for 4 years)

/*快速排序：以待排序元素中的第一个元素作为基准将带排序的元素分为三组 *大于基准元素为一组置于基准值的右边，小于基准值的元素为一组置于基准值的左边， *基准值为一组，这样就找到了基准元素的位置就确定了 *如此递归调用。直到每一组的low==high，即实现了排序的要求。 */ (/* Rapid Sort: the first element to be sorted in the element as a basis with with sorting the elements are divided into three groups* is greater than the reference element of a group is placed on the right side of the reference value, smaller than the reference value elements for a group of placed on the left side of the reference value,* reference value, a group, so that the location of the reference element is found it is determined* so recursive call. Until each group of low == high to achieve the requirements of the sort.* /)

使用非递归的方法遍历二叉树，可以直接运行。( Non-recursive binary tree traversal.)

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.)

说明：  图的相关操作：建立图，图的遍历，查找元素，删除元素等(Map-related steps: the establishment of map, graph traversal, find elements, delete elements, etc.)

用邻接表表示的数据结构，及DIJKSTRA算法实现的最短路径程序(adjoining table with the data structure and algorithm DIJKSTRA the shortest path procedures)

数据结构，关键路径问题，设计并实现关键路径的一种应用，采用图的算法(Data structure, critical path problem, using graph algorithm)

几个比较好的初级算法，初学者可以看一下思想，对算法入门(A few good elementary algorithms, beginners can look at thinking on algorithms entry)
