C语言实现外卖管理系统

本文为大家分享了C语言外卖管理系统的具体代码，供大家参考，具体内容如下

内容

说明（废话）：上学期写的课程设计，主题是外卖管理系统，希望可以模拟网上订餐，店家工作，专人管理的过程。并实现注册与登录以及基本信息的输出，因为个人比较懒，一直没有整理上去，今天得空，要是得到大家的宝贵意见的话，会不胜荣幸。

重点内容

  三端登录 ：分别为管理员，用户以及店主；两端注册，分别为用户以及店铺，其中店铺的注册成功需要得到管理员的审核。

•   管理员端可以查看店铺信息，店铺信息修改（分为增删改查），处理申请店铺，和修改本人信息。
•   用户端分为用户相关（为用户本人对自己信息的操作），查看订单，查看菜品，购买菜品，以及订单排序。
•   管理员端为增添菜品，删除菜品，修改菜品，查看菜品以及业绩查看（统计总订单与总收入）。

另外：

1. 店家注册需要的到管理员的认证，认证通过之后才可登录
2. 密码修改需要输入旧的密码，三次错误可以找回密码，输入手机号，若手机号匹配得当，则可产生三位数的随机验证码，输入验证码即可修改。
3. 对于已超过三分钟的订单不能修改，因为已经配送
4. 限制了用户的余额，当购买时余额不足时，需要进行账户的充值，而购买结束后，账户的余额也会相应的减少

以下为功能模块图：

以下为函数调用关系图：
