some problems about c++.(car.cpp)

二叉树的C++实现，成员可以自己调整，实现了各种修剪此树的方法：初始化，增加节点，删去节点，复制树，读取节点，遍历树(Binary tree in C++, members can make their own adjustments to achieve a variety of pruning this tree methods: initialize, add nodes, delete nodes, copy the tree, read the node, traverse the tree)

实现链表的一些操作，方便进行遍历，查找等程序(Operation, convenient linked list traversal, the search procedure)

POJ141的源代码，以空间换时间，速度很快很好用。(POJ141 the source code for time in space, fast easy to use.)

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.)

选择型结构c语言编程 (Choose the type of structure of C language programming)

1>实现可以随意浏览任一景点的介绍。（功能一） 2>可以给出任意两个景点的最短距离及其路线。（功能二） 3>可以查看任一景点热度，并可以对对所有景点热度（访问次数）进行排序。（功能三） 4>每个景点相关内容从文件读取，实现对文件操作的练习。 (1> implementations can feel free to browse introduce 任一景 points. (Function a) 2> You can give the shortest distance and route between any two attractions. (Function b) 3> You can view Renyi Jing point heat, and heat can all attractions (visits) to be sorted. (Function c) 4> each spot related content file reading, to achieve the file operations exercises.)

序列二次规划算法，能求解包含约束和无约束的问题，非常方便。(Sequential quadratic programming algorithm to solve constrained and unconstrained contain the problem, very convenient.)

说明：  可以实现判断二叉树是否为完全二叉树、判断两棵二叉树是否镜像对称、求一棵二叉树的一个最长枝等功能(Can determine whether the binary tree is complete binary tree to determine whether two binary mirror symmetry, one of the longest seeking a binary tree branches and other functions)
