大一C语言大作业_网吧收费管理系统

（一）系统的功能构成图

（二）系统的功能说明


序号	模块	功能	说明
1	卡管理	添加卡	输入卡号、密码、开卡金额等卡信息，将卡信息保存到data文件夹的card.txt文件中
2		查询卡	根据输入的卡号，查询卡号相同的卡信息，并以表格形式显示在控制台中
3		注销卡	根据输入的卡号、密码，将对应卡的状态改为注销，注销卡不能进行上机
4	计费标准管理	新增计费标准	输入计费标准的信息，将输入的计费标准保存到data文件夹的rate.txt文件中
5		查询计费标准	根据上机时间，查询对应的计费标准
6		删除计费标准	从计费标准文件data文件夹的rate.txt文件中，删除一条计费标准
7		修改计费标准	修改一条计费标准
8	计费管理	上机	根据输入的卡号、密码，判断该卡能否上机，如果能上机，则保存计费信息
9	计费管理	下机	根据输入下机卡的卡号，进行下机结算操作
10	费用管理	充值	给一条已经存在的卡进行充值。
11	费用管理	退费	将卡中余额返回给用户
12	查询统计	查询消费记录	查询一张卡在一段时间内的消费记录
13		统计总营业额	统计一段时间内，总营业额
14		统计月营业额	统计一年中，每个月上机次数、总营业额，将统计结果保存到文本文件中，并以列表形式显示在控制台中。
15	权限管理	添加管理员	超级管理员添加一个管理员信息
16		删除管理员	超级管理员删除一个管理员信息
17		配置权限	添加管理员时，配置管理员的权限
18	系统	登录	超级管理员和管理员登录系统
19	系统	退出	超级管理员和管理员退出系统

（三）系统的实现技术要求

必须使用链表描述系统的数据结构，使用文件保存数据。
要求每一项功能的实现必须以函数调用的形式完成。
