WHUT C语言计费（网吧）管理系统

计费管理系统

本项目模拟网吧计费管理系统,基于C语言实现.主要运用C语言文件、单链表、结构体基本操作
主要功能：
1.添加卡信息
2.查询卡信息
3.上机登陆操作
4.下机操作
5.卡充值操作
6.卡退费操作
7.查询统计
8.注销卡
9.退出
下面介绍各文件及其具体功能

未完全使用老师提供的三层结构：（每个方法首先调用card_file中卡信息文件读取函数获取卡信息链表方便判断）
添加卡片操作：menu.cpp调用add函数（文件中不存在该卡片）->card_service.cpp中addCard函数->card_file.cpp中saveCard函数(写入文件) 展示卡片信息

查询卡片操作:menu.cpp调用query函数（文件中存在该卡片）->card_service.cpp中queryCard函数->展示卡片信息

上机操作:menu.cpp调用login函数（文件中存在该卡片且未在上机删除注销状态）->
card_service.cpp中showchange函数->card_file.cpp中updateCard函数->更新文件中卡信息 展示上机信息

删除卡片操作:menu.cpp调用del函数（文件中存在该卡片且未在上机删除注销状态）->card_service.cpp中delCard函数->card_file.cpp中updateCard函数->更新文件中卡信息 展示卡片信息

因涉及到消费情况故调用billing_service.cpp 中函数
下机操作: menu.cpp调用Settle函数（文件中存在该卡片文件中存在该卡片）->billing_service.cpp中doSettle函数 将消费信息保存至二进制文件中->更新文件中消费信息展示下机信息

查询统计操作: menu.cpp中inQuirystat函数（提示用户操作选择）

统计总营业额:->调用billing_service.cpp中inQuiryTo函数->readInfo函数从二进制文件中读取消费信息->inQuiryTo函数计算总消费信息并返回
查询某卡消费记录:->调用billing_service.cpp中inQuiryMon函数->readInfo函数从二进制文件中读取消费信息->inQuiryMon函数读取消费信息卡号比较获得该卡消费金额

充值退费调用service.cpp中函数
充值操作:menu.cpp调用addMoney函数->调用service.cpp中addMoney函数->调用card_file.cpp中updateCard函数->更文件中卡信息

退费操作:menu.cpp调用reFundMoney函数->调用service中dofeFundMoney函数->调用card_file.cpp中updateCard函数->更文件中卡信息

Thoughts

程序已基本调试完成，但仍存在冗余部分。整体难度适中,主要是文件操作链表操作要熟悉,这让我明白了基础的重要性。日后应认真完成每一次实验,对于计算机专业的学生，编码能力与思考能力才是最重要的。
