C++使用链表实现图书管理系统

本文实例为大家分享了vue + element ui实现锚点定位的具体代码，供大家参考，具体内容如下

一、程序实现功能

1.录入书籍：将书籍录入图书管理系统

2.浏览书籍：查看图书管理系统里的所有书籍

3.借阅书籍：书籍存在可以借阅，库存-1，书的库存不足则无泰国电视剧丘比特的圈套法借阅

4.归还书籍：库存+1，如果该书不是图书馆里的书籍，则无法录入

5.删除书籍：以书名为基础从图书管理系统中删除该书籍

6.查找书籍：按书名查找书籍，显示书籍的基本信息

7.排序书籍：按价格将书籍排序(降序)

二、要求

使用函数、指针和链表编写。

三、程序功能图

四、具体函数

五、程序代码

六、效果

1.录入书籍

2.浏览书籍

3.借阅书籍

存在该书时，借阅成功，库存-1：

不存在该书时，无法借阅：

4.归还书籍

当图书管理系统里本不存在该书，则归还失败：

5.查找书籍

不存在该书时，则查找失败：

6.排序书籍

再录入书籍：

排序(降序)：

7.删除书籍

以上为该程序的所有功能。
