3.c语言图书管理系统
4.急求C语言编写的图书管理系统源代码，具体要求如下
基于B/S+MySQL+JDBC的源码书借阅管理系统（附：论文 源码 课件 数据库）
本设计以图书管理业务为核心，利用B/S架构、书源MySQL数据库和JDBC实现图书借阅管理系统的代码开发。系统采用eclipse作为前台开发工具，查书后台集成MySQL数据库，源码asp源码 会员重点在于需求分析与数据库详细设计。书源该系统旨在提供数据保存、代码修改、查书删除等功能，源码构建友好、书源高效的代码操作平台，为用户带来便捷的查书服务体验，激励人们接触与热爱阅读。源码
系统具备如下功能模块：
读者界面：登录注册、书源借阅还书、查询书籍、查看借阅历史与信息、查看排行榜、问题反馈及查询反馈结果。民间指标源码
管理员界面：图书、分类、读者信息的增删查，查看借阅信息、排行，处理用户反馈。
超级管理员界面：扩展管理员权限，管理管理员信息，为书店员工定制账号。
系统运行环境要求硬件配置及软件环境如下：
硬件：CPU需PIV1.6G以上，内存至少M，硬盘G以上。
软件：操作系统Windows，编译工具eclipse，JDK1.8，服务器Tomcat，JDBC驱动，数据库MySQL，前端框架bootstrap。咪咪兔源码
网络环境：运行在单位局域网内，确保服务器和客户端计算机连接。
安装与配置包括eclipse、Tomcat、MySQL的安装及JDK环境的配置。
功能演示如下：
登录界面：输入账号（学号/工号）、密码及验证码登录系统，根据账号识别用户身份并进入对应界面，未注册用户可快速注册或联系管理员添加账号。
系统主界面：包含图书查询、借阅信息、历史借阅、热门推荐、排行榜、反馈等模块。用户可修改个人资料、密码，退出系统。
图书查询功能：列出所有图书信息，网站源码截取支持按书名、作者、分类查询，点击借阅按钮完成借阅操作。
借阅信息展示：当前用户的借阅图书信息，包括借阅日期、还书日期，可延期需管理员操作，点击还书按钮完成还书。
借阅历史记录：展示用户历史借阅的图书信息，记录借阅与还书日期。
热门推荐：根据借阅次数实时排序，支持图书查询，点击借阅按钮完成借阅。
最佳读者排行：实时排序用户借阅量，可按ID、姓名、账号查询。
问题反馈功能：填写反馈内容，云通源码提交后可查看反馈状态（未解决或已解决）。
管理员功能界面：管理图书、分类、读者信息，查看借阅信息、排行，处理反馈。
图书管理功能：添加、修改、删除图书信息。
读者管理功能：添加、修改、删除读者信息。
图书分类管理功能：添加、修改、删除分类信息。
图书借阅信息管理：展示借阅信息，还书、延期操作。
图书归还信息管理：展示归还信息。
热门推荐功能：按借阅次数实时排序，支持查询与借阅。
读者反馈管理功能：查看、修改反馈状态，处理反馈。
系统支持源码、课件等配套资料的获取，提供Java和Python学习资料，鼓励资源共享与技术交流。
