拖动开发代码，关于pb 的

数据库实习的很好的课题-database attachment very good subject

这是我在英国的C语言导师自己所写的一个二叉树的程序。-This is a binary-tree programme written by my tutor in England.

利用c++写的双向链表操作，有头插入，尾插入，中间寻找“朋友“的方式插入，适合简单数据结构分析

功能强大的查询系统操作方便易懂好用不会繁琐数据库也强大-Powerful query system will not be easy to use easy-to-understand red tape is also a powerful database

最小二乘法曲线拟合的经典算法，做过特征数检验，只需调用fit，文件中其他函数被fit调用，其中个输入输出变量均以给出详细说明。-least squares curve fitting classic algorithms, the number of tests done, just call fit, the paper other function to be fit Call, 000 input and output variables were presented in detail.

利用C++对MYSQL进行数据读，写，及修改. 需要有mysql.h 头文件   数据库结名为person, 表名为 mm, 表结构如下：  字段             类型 device_id       int sav_value      int sav_date        datetime

这是一个PB小程序　是实现模糊查询的.这是一个PB的小程序，实现模糊查询的 这是一个PB的小程序，实现模糊查询的-PB This a small program is vague inquiries. This a small program PB, Fuzzy inquiry, which is a PB of small programs to achieve fu zzy inquiry, which is a PB of small programs to achieve fuzzy inquiry, which is the one PB small program for the realization of fuzzy

这是李春葆的《数据结构全书》的源码，亲测运行通过，比较适合自学数据结构，好东西当然不能独吞了，好评呦，亲！适合考研的同同学

图的深度遍历，用二叉树实现，输入时要遵循二叉树的顶点和边数的对应关系-traverse the depth map, using binary tree realize that the importation of binary tree to be followed when the number of vertices and edges of the relationship
