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.)

校园导航系统 1） 校园景点介：绍介相关景点的有关详细信息。 2） 最佳路线查询：查询校园中任意两点之间所有路线，并提供两点间最短的简单路径。 3） 关节点查询：提供校园图的关节点查询。 4） 多景点最佳路线查询：提供多个景点的最佳线路查询，即求途径这个景点的最佳路径。 (Campus Navigation System 1) campus attractions Introduction: Shao Jie-related attractions for more information. 2) The best route query: Query on campus all the routes between any two points, and provides a simple shortest path between two points. 3) joint points: the key points to provide the campus map queries. 4) The best route queries more attractions: multiple sites to provide the best route queries, that is seeking ways to this spot the best path.)

停车场管理系统 c语言实现 停车场拥有M个车位和一条进入停车场的便道，便道上最多停放N辆汽车。汽车要想进入车位，首先进入便道等候。若有空闲车位，则停车入位，否则在便道继续等候，直至有车位空出。若便道已经停满等候的汽车，后到达的汽车只能离开，选择其他停车场。设计一个停车场管理系统，模拟停车场的运作，并统计停车场的收入。(Parking Management System with M c language parking spaces and a sidewalk into the parking lot, parked up on the sidewalk N cars. To enter the car parking spaces, first into the pavement waiting. If free parking, the parking into place, or in the sidewalk to wait until the needed spot. If the sidewalk is already full of parked cars waiting, after the arrival of the vehicle to leave, choose a parking lot. Designing a car park management systems, simulation parking operations and parking revenue statistics.)

约瑟夫环（约瑟夫问题）是一个数学的应用问题：已知n个人（以编号1，2，3...n分别表示）围坐在一张圆桌周围。从编号为k的人开始报数，数到m的那个人出列；他的下一个人又从1开始报数，数到m的那个人又出列；依此规律重复下去，直到圆桌周围的人全部出列。通常解决这类问题时我们把编号从0~n-1，最后结果+1即为原问题的解。 (Josephus (Josephus problem) is the application of a mathematical problem: Given n individuals (with numbers 1,2,3 ... n respectively) sitting around a round table. From the number of people gettin k, number of the m man out of the line he s the next person and a number of gettin number to m the man was out of the line and so the law is repeated until the round table were all out of the column. We numbered 0 ~ n-1, the final result is the original problem solution+1 usually solve these problems.)

说明：  贪心方法是一种改进了的分级处理方法。它首先根据题意，选取一种量度标准。然后按这种量度标准对这n个输入排序，并按排序一次输入一个量。如果这个输入和当前已构成在这种量度意义下的部分最优解加在一起不能产生一个可行解，则不把此解输入加到这部分解中。这种能够得到某种度量意义下的最优解的分级处理方法称为贪心方法。(greedy method is an improvement of the classification methods. According to its first title Italy, and a selection of standards of measurement. Then, under such a standard measure of this sort n input, with an input an order volume. If the input current and constitutes a measure of significance in this part of the optimal solution together not produce a feasible solution. this solution will not put this added to the importation of decomposition. This can be a meaningful measure of the optimal solution hierarchical method, known as greedy method.)

一．问题描述 对2006年度全国80多个城市的每天空气质量状况进行查询、排序等操作。 空气质量状况对象包括城市代码、城市名称、首要污染物、污染指数、污染物级别、空气状况、年、月、日 二、实验要求 1． 普通查询：输入城市名称和城市代码，分别查询该城市每天、每周、每月、每季度和全年的空气质量状况 例子：查询太原市2006年第8周的空气质量状况 2．统计查询： （1）输入城市名称和城市代码，分别查询该城市每周、每月、每季度和全年的空气质量为优、良、轻微污染、轻度污染、重污染的天数 例子：查询石家庄市2006年第2季度空气质量为轻微污染的总天数 （2）根据时间查询空气质量状况：输入周编号、月编号、季度编号或年编号，以及空气质量为优、良、轻微污染、轻度污染、重污染的天数，查找相应的城市名称 例子：查询2006年5月，空气被轻度污染3天以上的城市有哪些？ 3．排序查询 （1）输入周编号、月编号、季度编号或年编号，查询城市空气质量的排行榜 例子：查询2006年第6周，全国空气平均质量最好的前20个城市为哪些？ 三、数据文件 Data.txt(one. Problem Description of the air quality day in 2006 more than 80 cities nationwide query, sorting and other operations. Air Quality objects include city code, city name, the primary pollutant, pollution index, contaminant level, air condition, year, month, day two, experimental requirements 1. General Queries: Enter a city name and city codes, each query in the city daily, weekly, monthly, quarterly example air quality and full year: Queries air quality in Taiyuan first eight weeks of 2006 2. Statistical inquiry: (1) enter a city name and city codes, each query in the city weekly, monthly, quarterly and annual air quality as excellent, good, slight pollution, light pollution, heavy pollution days example: inquiry Shijiazhuang City in 2006 second quarter, the air quality is the total number of days a slight pollution (2) according to time of the query air quality conditions: enter the week number, month number, quarter number or in number, and the air quality is excellent, good, sli)
