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.)

另外一个可以实现线性表的程序，简单的操作，值得初学者的借鉴(Another table can achieve a linear process, simple to operate, it is worth drawing beginners)

基于MFC平台，实现多功能计算器，可求解复杂表达式，主要实现为数据结构中链表和数组，对于要熟悉链表和数组的初学者有很帮助。(Based on the MFC platform, to achieve multi-function calculator, can solve complex expressions, the main realization of the data structure for the list and array, to be familiar with the list and the array of beginners helpful.)

直接插入排序算法验证。 快速排序算法验证。 直接选择排序算法验证。 (Direct insertion sort algorithm validation. Quick sort algorithm validation. Direct selection sort algorithm validation.)

poj 实现堆结构的源代码。。。话说其实没什么实际功能好么(poj achieve heap structure of the source code. . . In fact, the actual function of saying okay nothing)

说明：  动态规划是用空间换时间的一种方法的抽象。(Dynamic programming is to use space in time a method of abstract.)

数据结构中图的遍历Data structure traversal of center(Data structure traversal of center)

简单的一个链栈.即用链表实现的一个栈。可以做简单的插入、删除、查找等操作(this is a simple C++ program )

Polynomial基于数据结构的思想,文件比较小,可以直接运行(Polynomial based on the idea of ​ ​ data structures, file is relatively small and can be run directly)

设有一头指针为L的带有表头结点的非循环双向链表，其每个结点中除有prev（前驱指针），data（数据）和next（后继指针）域外，还有一个访问频度域freq。在链表被起用前，其值均初始化为零。每当在链表中进行一次Locate(L,x)运算时，令元素值为x的结点中freq域的值增1，并使此链表中结点保持按访问频度非增（递减）的顺序排列，同时最近访问的结点排在频度相同的结点的最后，以便使频繁访问的结点总是靠近表头。试编写符合上述要求的Locate(L,x)运算的算法，该运算为函数过程，返回找到结点的地址，类型为指针型。(Has a head pointer is non-circular doubly linked list L with a header node, each node in addition to prev (precursor pointer), data (data) and next (successor pointers) outside, there is an access frequency degree domain freq. Before the list was hired, their values are initialized to zero. Whenever carried out in the list once Locate (L, x) when the operation, so that the element node x is the value in freq domain by one, and keep this list in the node-access frequency of non-increasing (decreasing) the order, while a recent visit to the nodes in the same row of the frequency of the last node, so that the nodes are frequently accessed tables are always near the head. Locate (L, x) algorithm is prepared in accordance with the above requirements of the test operation, the operation as a function of the process, return to find the address of the node of type pointer.)
