怎么用C語言實(shí)現(xiàn)圖書管理系統(tǒng)

這篇文章主要介紹“怎么用C語言實(shí)現(xiàn)圖書管理系統(tǒng)”的相關(guān)知識(shí)，小編通過實(shí)際案例向大家展示操作過程，操作方法簡(jiǎn)單快捷，實(shí)用性強(qiáng)，希望這篇“怎么用C語言實(shí)現(xiàn)圖書管理系統(tǒng)”文章能幫助大家解決問題。

設(shè)計(jì)要求

設(shè)計(jì)圖書管理系統(tǒng)

要求如下：

1.對(duì)書名，作者，編號(hào)，出版單位，出版日期，類別，存放位置進(jìn)行添加、刪除、修改
2.查詢相關(guān)信息
3.保存所有信息
