這篇“怎么用C語言實現共享單車管理系統”文章的知識點大部分人都不太理解,所以小編給大家總結了以下內容,內容詳細,步驟清晰,具有一定的借鑒價值,希望大家閱讀完這篇文章能有所收獲,下面我們一起來看看這篇“怎么用C語言實現共享單車管理系統”文章吧。

1.功能模塊圖;

怎么用C語言實現共享單車管理系統

2.各個模塊詳細的功能描述。

1.登陸:登陸分為用戶登陸,管理員登陸以及維修員登錄,登陸后不同的用戶所執行的操作不同,權限不同。

(1)管理員登錄:管理員登陸之后,可使用鍵盤的上下鍵來控制菜單上的選項,管理員權限不多,可執行最多的操作,可以對單車進行投放,刪除,修改,查找,車牌號排序,查看所有單車信息,所有用戶信息,管理員能通過或駁回正在申請注冊的維修員,還可以查看完全通過認證的維修員。   

(2)用戶登錄:用戶登錄時需要輸入注冊時的賬號和密碼,或者是之前注冊的有效賬號及密碼,用戶可以查看自己附近的車,立即用車當車密碼出現的時候就開始計時了,還車后停止計時,一個時間段內沒有還車不能再借車了,另外還有報修,報修的信息會上傳到維修員那里,還可以查看自己的信息修改自己的信息,當用戶賬號不足100元時不能再借車了,所以還有充值這一項功能。

(3)維修員登錄:維修員登錄時也需要賬戶和密碼(管理員認證的),維修員權限較大,只可以查看自己的信息,修改自己的信息,以及查看用戶報修的單車信息。

2.注冊:注冊有用戶注冊和維修員注冊。

(1)用戶注冊:用戶注冊時,手機號即為登錄賬戶,有查重的功能,每個手機號只能注冊一個用戶,設置密碼時,系統會對你的密碼的安全系數進行評分,以及需要確認密碼,兩次不一致注冊失敗,輸入年齡,年齡不滿10歲不可注冊,注冊成功后需要起一個用戶名,需要綁定充值卡,首次充值200元,即可登錄。

(2)維修員注冊:維修員注冊時,手機號即為登錄賬戶,也有查重的功能,每個手機號只能注冊一個用戶,設置密碼時,系統會對你的密碼的安全系數進行評分,以及需要確認密碼,兩次不一致注冊失敗,后需要起一個用戶名,輸入年齡,年齡不滿18歲不可注冊,但此時并沒有注冊成功,只是完成了申請,不可登錄,等待管理員認證,通過,注冊成功,即可登錄,駁回,注冊失敗。

3.增加:增加單車信息到文件 中。

4.修改:修改單車信息,修改用戶個人信息,修改維修員個人信息。

5.刪除:刪除單車。

6.查找:查找單車并按所選順序查看。
