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)

建立链表的算法:
新节点链入表尾建立链表:
动态分配第一个节点变量;
用指针head 妥善保存链表第一个节点的地址值;
依次动态分配一个新节点变量;
将上一个节点的指针域指向新生成的节点;
循环3),4)步骤,直到所有节点均连入链表;
将最后一个节点的指针域赋值为0;
(Establish the list of algorithms:
The new node links footer build list:
Dynamic allocation of the first node variable
Keep the list head pointer of the first node address value
In order to dynamically allocate a new node variable
The domain of a node pointer to the new generation of nodes
Cycle 3), 4) step, until all nodes are connected to the chain
Pointer field will last node assigned to 0 )
