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)

Task1-trial--10211281--zly
描述:足球俱乐部包括球员、普通行政人员。球员有姓名、年龄、能力、年薪、转会费、进球总数、服役年限等重要参数;普通行政人员有姓名、年龄、能力、年薪等参数。你需要给相关管理机构开发一个管理程序,实现对众多足球俱乐部管理的基本功能。具体功能包括:
a) 俱乐部的增删改查,俱乐部的属性包括名称、现金、其下人员;
b) 可以对所有球员的各项属性进行简单搜索,支持输入多个条件,条件之间用&&连接,例如:
i. “年龄不大于25且服役年限大于5年且进球数大于100的球员”,查询表达式:!(@age>25) && @experience>5 && @kick>100
c) 支持球员在不同俱乐部间的买卖,买卖需符合以下条件:作为买方的俱乐部的现金>=球员的转会费,交易完成后,卖方将得到转会费。
要求:
d) 必须采用面向对象的方式,使用类组织数据结构,并注意类的继承关系;
e) 在题目要求基础上可以自行扩展功能,提供扩实用扩展功能者适当加分(加分不超过5分)。
