數據結構課程設計(基於C) 圖書管理系統
懸賞分：100 - 離問題結束還有 14 天 23 小時
【問題描述】
圖書管理基本業務活動包括，對一本書的采編入庫、清楚庫存、借閱和歸還等等。試設計一個圖書管理系統，將上述業務活動藉助於計算機系統完成。
【基本要求】
（1） 每種書的登記至少包括書號春前好書名作者現存量總庫存量5項
（2）對書號建立索引表（線性表）以提高查找效率
（3） 系統要實現的操作及其功能定義如下：
1 采編入庫：新購入一種書，經分類和確定數好之後登記到圖書館賬目中去。如果這種書在賬戶中已有，則只將總庫存量增加。
2借閱：如果一本書的現存量悔友大於零，則借出一本，登出借閱者的圖書證扒鉛號和歸還日期
3歸還：注銷對借閱者的登記，改變該書的現存量
