图书管理系统c 项目

图书管理系统C项目介绍

图书管理系统C是一个简单的计算机程序，用于管理图书馆的图书。这个程序可以让用户查看和添加新的图书，修改和删除已有的图书，以及搜索和浏览图书。本程序使用了C语言作为编程语言，并使用了一个Windows操作系统。

程序的主要功能和界面如下：

1. 用户登录：用户可以通过用户名和密码登录系统。

2. 图书添加：用户可以通过输入图书的书名、作者、出版社、ISBN号码等信息来添加新的图书。

3. 图书修改：用户可以通过输入新的书名、作者、出版社、ISBN号码等信息来修改已有的图书。

4. 图书删除：用户可以通过输入书名、作者、出版社、ISBN号码等信息来删除已有的图书。

5. 图书搜索：用户可以通过输入关键词来搜索已有的图书。

6. 用户管理：用户可以查看自己的库存，并查看其他用户的库存。

下面是程序的主要代码：
