您好,登錄后才能下訂單哦!
本篇文章給大家分享的是有關C語言中怎么實現一個外賣管理系統,小編覺得挺實用的,因此分享給大家學習,希望大家閱讀完這篇文章后可以有所收獲,話不多說,跟著小編一起來看看吧。
重點內容
??三端登錄 :分別為管理員,用戶以及店主;兩端注冊,分別為用戶以及店鋪,其中店鋪的注冊成功需要得到管理員的審核。
??管理員端可以查看店鋪信息,店鋪信息修改(分為增刪改查),處理申請店鋪,和修改本人信息。 ??用戶端分為用戶相關(為用戶本人對自己信息的操作),查看訂單,查看菜品,購買菜品,以及訂單排序。 ??管理員端為增添菜品,刪除菜品,修改菜品,查看菜品以及業績查看(統計總訂單與總收入)。
另外:
1. 店家注冊需要的到管理員的認證,認證通過之后才可登錄 2. 密碼修改需要輸入舊的密碼,三次錯誤可以找回密碼,輸入手機號,若手機號匹配得當,則可產生三位數的隨機驗證碼,輸入驗證碼即可修改。 3. 對于已超過三分鐘的訂單不能修改,因為已經配送 4. 限制了用戶的余額,當購買時余額不足時,需要進行賬戶的充值,而購買結束后,賬戶的余額也會相應的減少
