数据结构教程代码 严蔚敏 上机实验操作代码

求解一个最短路径问题程序，可以参考一下求一个Dijkstra优化算法！ 谢谢了 目的是求给定两点之间的最短距离 或者改一下我的程序也行 -shortest path to solve a problem of procedure, can seek a reference Dijkstra algorithm optimization! Thank you, the purpose is scheduled for 2:00 to the shortest distance between or change my procedure OK

学生管理系统功能的信息量大，数据安全性和保密性要求最高。本程序可实现这些功能。1)输出学生成绩单2)按姓名查询3)增加学生4)删除学生5)按班级修改学生成绩6)显示不及格学生成绩7)按平均成绩排序并输出成绩

VS 2013 编译。用的是ADO.的技术 访问SQL2008的数据库。是做课程设计的一部分。重新包装了类，更易使用                                                               

[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

主要是严蔚敏版《数据结构（C语言版）》第二章线性表中算法的C语言实现，能够帮助初学者更好的理解这部分内容~~~

c语言数据结构源代码（全）相当经典-c language data structure source code (all) is a classic

树的四种遍历方式，中叙，前序，后序和按层遍历算法，前三个用递归很好实现，最后一个复杂点。-tree traversal of the four, China and Syria, the former sequence after sequence and by layer traversal algorithm, the former three Recursive properly achieved, Finally a complex point.

一些常用的几何算法的C++实现,包括两点确定一条直线,两点间距离,点直线距离, 海伦公式求三角形面积,判断直线相交等-some common geometric algorithm C achieved, including two identified a straight line, the distance between two points, point straight distance Helen formula for triangle area, as judged straight intersection
