用C做的括号匹配程序,可以检测用户输入的括号是否匹配并给出提示-C matching brackets do procedures, the user can input the brackets and whether the match is suggested

用C++写的寻找公共祖先，实现树的先序后序中序层次遍历，内有实验报告可以参阅。-C wrote for the public ancestors, the first realization of the tree sequence after sequence traversal sequence level, there are experimental report can be found.

数据结构算法，图最短路径-data structure algorithm, the shortest path map

外部排序程序，foxpro的DBF文件中某个字段的程序，特点是可以指定排序内存大小，但可以排序超级大的文件远远超出机器内存，采用快速排序加失败树合并算法，排序中会产生很多临时小文件。修改后可用于任何文件字段排序。-External sort procedure, foxpro of DBF files in a field procedure, and there is a sort of memory you can specify the size, but you can sort super large files far beyond the machine memory, the use of quick sort algorithm plus the failure of the merger tree, sorting will produce many temporary small files. The revised document can be used for any sort by that field.

This a simple database management system. It doesn t use any other code (i.e. ODBC, ADO, etc.) and has it s own database file format. I wrote it because I found the other DBMSs code too bulky and hard to debug. It s designed for small applications and I doubt it could handle anything on a large scale. A sample program included in the .zip shows how everything works. The database project is a library project, so you ll have to compile and link with the .lib file to get everything working. Pros: - You have the source code so you know exactly what it is doing - Database files are very small - Small and fast code Cons: - Can t handle large amounts of records (more than 65000ish) - Doesn t support SQL (you have to search the database by cycling through the records and testing them against your constraints) - Each database file can only have one table. -This a simple database management system. It doesn t use any other code (i.e. ODBC, ADO, etc.) and has it s own database file format. I wr

这是一个用于计算最小生成树的程序。当人们逐个输入每条边的权，再点击生成，便能得到这个图的最小生成树。-This is a used to calculate the minimum spanning tree procedure. When people enter one by one each side of the right, then click generate, will be able to get this graph minimum spanning tree.

最短路径查询,用的是ESRI公司arcobject组件开发的,已经作成dll,用起来非常的方便-Shortest Path inquiries, the company is ESRI arcobject development of the components, make dll with it is very convenient
