无环连通图G=(V, E)亦称为自由树T，其直径是树中所有顶点之间最短路径的最大值，设计一个算法求T的直径(Acyclic connected graph G = (V, E) is also known as free tree T, whose diameter is the tree of shortest paths between all vertices maximum design an algorithm for the diameter of T)

总结了10种排序的方式。用代码加以实现。(the ten way of Line up a preface)

建立试题库文件，随机产生n个题目； 题目涉及加减乘除，带括弧的混合运算； 利用栈求解表达式的值； 随时可以退出； 保留历史分数，能回顾历史，给出与历史分数比较后的评价( The establishment of test database file, the subject of n randomly generated topics related to addition, subtraction, mixed operations with parentheses use the value of the expression stack solution ready to quit to preserve the historical scores, can look back at history, and history gives the comparison of scores Evaluation 保留历史分数，能回顾历史，给出与历史分数比较后的评价)

说明：  由C程序实现的 数学上 滑雪问题 的代码实现，供大家学习用(Ski problem code for all to learn to use)

数据结构中，运用链表实现四则括号运算等，运行在VC控制台上。(Data structure, the use of chain operations to achieve four brackets, etc., running in the VC console.)

本实验设有一个线性表，分别实现数组结构存储的原地逆置。为数据结构课程必做实验。(This experiment has a linear form, respectively, to achieve the storage array structure in situ reverse home. For the data structure courses will do the experiment.)

数据结构上机操作实验的实验1，线性表的基本操作！！！(the basic operation of sq of date structure)

设计一个表达式求值的程序。该程序必须可以接受包含（，），+，-，*，/的中缀表达式，并求出结果。如果表达式正确，则输出表达式的结果；如果表达式非法，则不输出或输出其他字符。(Design an expression evaluation procedures. The program must accept (,), including +, -, *, / the infix expression, and the results obtained. If the expression is correct, the output of the expression is output; if the expression is illegal, no other characters are output or exported.)

说明：  定义一个类SortArray继承自MyArray，在该类中定义函数sort实现排序功能。 定义一个类ReArray继承自MyArray，在该类中定义函数reverse实现逆转功能。 定义一个类AverArray继承自MyArray，在该类中定义函数Aver实现求解整数的平均值。 定义NewArray类，同时继承了SortArray、ReArray和AverArray，使得NewArray类的对象同时具有排序、逆转和求平均值的功能。在继承的过程中声明为虚基类，体会虚基类在解决二义性问题中的作用。 (Define a class SortArray inherited from MyArray, defined in the class sorting function sort implementation. Define a class ReArray inherited from MyArray, define the function in reverse to achieve such reversal function. Define a class AverArray inherited from MyArray, defined in the class to solve integer function Aver achieve the average. Defined NewArray class, and inherits SortArray, ReArray and AverArray, making the object of both NewArray class sorting, reversing, and the mean value of the function. In the process of succession declared as virtual base classes, virtual base class experience in resolving ambiguities of the role.)

数据结构与算法分析的 C++检索代码，很经典(the code of Data structure)
