在线考试系统是为不同学生提供在线考试。 使用 PHP 构建，  wamp 服务器包含登录表单，注册表单， 和数据库维护，可以删除或者插入数据

[问题描述] 将N个关键字去整数的记录进行整序， 以使所有关键字为非负数的记录排在关键字为负数的记录之前，要求使用最少的附加空间，且算法的时间复杂度为O（N） [输入] 待排序记录个数，各关键字的值。 [输出] 关键字从正负分开，正数在前 [存储结构] 待排序记录顺序存储。 [算法的基本思想] 快速排序算法每次任取一个记录的关键字为标准，将其余记录分为两组将，N个关键字去整数的记录进行整序， 以使所有关键字为非负数的记录排在关键字为负数的记录之前。 #include using namespace std #define MAXNUM 100//设文件的最长可能长度 void sort(int* keys, const int len)//排序 -[Problem Description] N keyword to the integer sequence the entire record. keyword so that all non-negative Records with the keyword for the negative record, at least require the use of the additional space and time complexity of the algorithm is O (N) [imported] to be sort record number, The value of the keyword. [Output] keyword separate from the pluses and minuses are several former [storage structure] scheduling records to be stored sequence. [Algorithm for the basic idea] quick sort algorithm each time a record for any keyword as a standard, The remaining records will be divided into two groups, N-keyword

数据库的一点点小常试 转别人的希望哪个有收获 谢谢大家哦-The database a little bit of small regular test to others which have a harvest of hope Oh I would like to thank everyone

C++ Builder程序员学习数据结构第3章-Builder C programmers to learn data structure Chapter 3

用动态规划法求两个字符串 A="xzyzzyx"和 B =”zxyyzxz“的最长公共子序列(For two strings A dynamic programming method = " xzyzzyx" and B = " zxyyzxz" the longest common subsequence)

此程序还不能对字符串排序，望能予以改进-A general soring program.*It can t sort string, and need to be improved.

二叉搜索树的生成和查找节点，北大《数据结构与算法》教材的习题(The generation and find nodes of a binary search tree, Peking University, " Data Structures and Algorithms" textbook exercises)

大整数乘法的详细实行 比如说1246*2566用此法可降低时间复杂度并且能过有效算出-large integer multiplication detailed implementation of the 1246* 2566 for instance, tried to use this method can reduce the time complexity and can Guo calculated effective

说明：  方便开发人员理解数据结构和算法分析的资料，包含源码配合了解(It is convenient for developers to understand data structure and algorithm analysis, including source code cooperation.)

C#编写的OleDb数据库连接通用类库，对我很有参考价值，希望对你也有用-OleDb prepared by the General Class Database Connection, I was useful, and I hope to you also useful
