本代码主要实现了哈希表的设计，完成了哈希函数的相关要求。(The code is designed to achieve a hash table, the completion of the relevant requirements of the hash function.)

数据结构简单的课程设计交通换乘算法,里面有零次换乘与一次换乘(Simple structure, curriculum design data traffic transfer algorithm, which have zero time transfer and a transfer)

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)

链表的建立及相关处理，包括排序，删除，初始化，增加，删除等等，且程序已运行通过。(The establishment of a linked list and related processing, including sorting, delete, initialization, increase, delete, etc., and the program has been run through )

开括号和比括号的匹配，数据结构内容，很不错(More than brackets and brackets to open the match, the contents of data structure)

队列的一般数据结构 队列的创建 删除 修改 取数据等等(The general data structure queue queue to take the data and so create delete modify)

利用栈完成算术表达式求值：从键盘或文件中输入算术表达式，计算其结果并显示。要求处理过程为：（1）转换为后缀表达式并输出；（2）对后缀表达式求值并输出。 输入的表达式中可以有整数、实数、括号，运算符包括+、-、*、/、#（代表单目负）。可以多次输入不同的表达式进行计算，直到用户选择“退出”。栈的基本操作可以自己实现，也可以使用系统提供的STL实现。 (Done using an arithmetic expression evaluation stack: file input from the keyboard or an arithmetic expression, calculate and display the results. Requirements process: (1) to postfix expression and output (2) evaluation of the postfix expression and output. Enter the expression can be integers, real numbers, parentheses, operators including+,-,*,/,#( representatives unary minus). You can enter several different expressions are evaluated until the user selects " Exit." Stack can implement the basic operations, you can also use the system implementation of the STL.)

计算点到直线的距离．输入两点坐标确定一个直线，再输入一个点的坐标，计算该点到直线的距离．(Calculated point to the straight line distance. Enter the coordinates of two points determine a straight line, and then input the coordinates of a point, to calculate the straight-line distance between points.)
