## 项目简介
2 years ago
本系统是程序设计与问题求解课程设计项目,实现了图书管理 CSV 格式数据文件的读取和保存以及数据的增删改查CRUD等功能。项目采用 C 语言编程实现,在 VS Code 集成开发环境IDE中用 GCC 进行编译。系统采用模块化设计,程序结构清晰,采用菜单驱动的命令行界面,操作便捷,能够用 CSV 格式读取和保存数据,通用性强,能够用图表展示数据,直观清楚。

## 关于图书管理系统
建立一个图书馆管理系统,可以处理以下对象:
1图书馆基本信息
2图书馆的书籍
3图书馆管理员
4读者信息
### 需求分析
1查询图书馆的总信息
2查询图书馆藏书信息
3存入新书
4旧书处理
5根据书名检索书刊信息
6查询读者的借阅信息
7查询读者信息
8读者借书
9读者还书
10文件保存
11从文件读取
## C1函数模块

## 概要设计
系统主要为开始界面和数据处理两大模块
开始界面即显示主要功能
数据处理包括:
查询图书馆的总信息
查询图书馆藏书信息
存入新书
旧书处理
根据书名检索书刊信息
查询读者的借阅信息
查询读者信息
读者借书
读者还书
文件保存
从文件读取
上述各模块通过主程序main进行调用系统模块图如下:
