這篇文章將為大家詳細講解有關C語言如何實現圖書管理系統，小編覺得挺實用的，因此分享給大家做個參考，希望大家閱讀完這篇文章后可以有所收獲。
開發一個圖書信息管理系統，圖書信息包括：圖書編號、書名、作者、出版社、類別、出版時間、價格等基本信息（也可以根據自己情況進行擴充，比如是否借出、庫存量等）。使之能提供以下基本功能：
（1）圖書信息錄入功能(圖書信息用文件保存)－－輸入
（2）圖書信息瀏覽功能－－輸出
（3）查詢功能(至少一種查詢方式)、排序功能(至少一種排序方式)：
①按書名查詢
②按作者名查詢 按照價錢排序 按出版時間排序等等
（4）圖書信息的刪除與修改
擴展功能：可以按照自己的程度進行擴展。比如
（1）簡單的權限處理
（2）報表打印功能
（3）甚至根據自己情況，可以加上學生信息，并擴充為圖書借閱系統。
（4）模糊查詢
（5）綜合查詢
（6）統計功能 比如統計處某一類別的圖書信息 或 篩選出小于指定數量庫存的圖書信息等等。
1 圖書錄入可以錄入圖書名，作者，出版社，出版日期，價格！錄入圖書編號時函數就會判斷此 編 號是否存在,若存在不能成功錄入!
2 圖書瀏覽可以瀏覽全部圖書！
3 圖書查詢提供按圖書編號模糊查詢，按圖書名關鍵字查詢，按圖書編號精確查詢，按圖書名精確 查詢！模糊查詢和關鍵字查詢事通過比價字符串的相似度而實現的!
4 修改刪除圖書可以通過圖書查詢來查詢操作的圖書編號，通過編號操作！函數會提示用戶是否調 用圖書查詢來找到自己想要操作的圖書的編號。如果某一本圖書已經被借閱那么用戶就不能刪 除 該圖書！
5 借閱圖書通過學號和圖書編號進行借閱！如果該學號是第一次借閱那么會提示用戶輸入自己的姓 名,并存入student.txt，方便以后借閱與歸還！
6 歸還圖書先提供學號，然后程序會輸出該學號借閱的所有圖書，然后再通過編號歸還！
7 借閱查詢可查詢某個學生已借但未歸還的圖書！
先建立結構體，定義結構體成員
