COM中使用SAFEARRAY数组例程，代码中给了两种数组的用法，一种是字符串数组，另一种是自定义数据结构数组。 (use COM SAFEARRAY array routines, a code for the use of two arrays, a string array, and the other is from the definition of array data structure.)

任务：实现Dijkstra算法 工程名：Project_ShortestPath 要求：实现Dijkstra算法，算法主体写在CGraph类中；要求是从command窗口中输入源节点编号，并在command窗口中输出从源节点到所有目的节点的最短路长及最短路。注：要输出整条路径，而不仅仅是前一跳，也不允许逆序输出。 (Task: Dijkstra' s algorithm to achieve the project name: Project_ShortestPath requirements: achieve Dijkstra algorithm, the algorithm written in the body CGraph class requires input from the command window, the source node number, and in the command window, all of the output from the source node to the destination node shortest long and the shortest. Note: To export the entire path, not just before the jump, do not allow reverse output.)

二叉树实现，整个包为VS工程。包含了二叉树的基本功能(Binary Tree, the entire package is VS works. Contains the basic functions of the binary tree)

数据结构课上老师布置的5个小项目的源代码，分别是汽车过河，一元多项式，迷宫，日历，BFS_DFS(failed to translate)

说明：  该程序实现二叉树的遍历功能，能够打印出二叉树的节点(The program realization of the binary tree traversal function, is capable of printing out the binary tree node)

最小生成树C语言程序，提供给喜欢编程以及数学建模的同学(Minimum spanning tree C language program)

实现对二叉树的操作：建树、遍历、求层高、叶子数和结点数等(binary tree)

c语言的一些小李子，初学c的朋友有帮助，主要有顺序表、二分查找、二叉树、单链表等等(Some Survival Song c language, c beginner to help a friend, there are sequence tables, binary search, binary tree, a single linked list, etc.)

参加数学建模的同学很可能会遇到这套题。本程序采用链表进行编写，很方便地解决了小白鼠问题。(Mathematical modeling of the students participating are likely to encounter this question, the program uses the list to solve the problem of mice, very convenient.)

求有向图的最短路劲，根据所给图的边长和顶点，建立有向图，以邻接表的方式存储，并编写程序求从有向图任一点出发的最短路径(according to the graph with sides and vertex, establish a directed graph, and write a program find the shortest path from one of the point of the chart )
