## 项目简介
|
|
|
|
|
|
|
|
|
|
|
|
本系统是自建设计项目，实现了图书管理中的借书和还书，查询书籍，以及书籍的添加、删除和显示所有书籍等功能。项目采用 C/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
|
|
|
|
|
|
设计一个图书管理系统，要求采用命令行菜单界面进行交互，具备查书、借书、还书、打印书籍 、添加、删除等基本功能，能够以表格和图表形式展示数据，采用 CSV 格式保存数据。
|
|
|
|
|
|
|
|
|
|
|
|
\
|
|
|
|
|
|
系统的功能性需求：
|
|
|
|
|
|
- 数据的查书、借书、还书、打印书籍、添加、删除展示。
|
|
|
|
|
|
|
|
|
|
|
|
系统的非功能性需求：
|
|
|
|
|
|
- 菜单驱动的命令行交互界面。
|
|
|
|
|
|
|
|
|
|
|
|
## 需求分析

# 概要设计
|
|
|
|
|
|
系统主要分为用户界面和数据处理两大模块。
|
|
|
|
|
|
|
|
|
|
|
|
用户界面模块包括系统初始化（init），显示菜单（display_menu），选择菜单命令
|
|
|
|
|
|
（make_choice）、确认（confirm）、退出（quit）等子模块。
|
|
|
|
|
|
数据处理模块包括 添加图书( DoAddBook ) 、查找图书( DoFindBook ) 、删除图书( DoDeleteBook ) 、打印所有图书( DoPrintBook ) 、归还图书( DoRepaidBook ) 、借用图书 ( DoBoorowBook ) 、修改图书( DoReviseBook ) 、排序图书( DoSortBook )等子模块。
|
|
|
|
|
|
|
|
|
|
|
|
其中查询、添加、修改和删除数据还会用到根据编号查询数据的方法（find）。
|
|
|
|
|
|
上述各模块通过主程序（main）进行调用，系统模块图如下。
|
|
|
|
|
|
```
|
|

|
|
|
|
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
|
各模块的主要功能如下：
|
|
|
|
|
|
## main
|
|
|
|
|
|
系统主函数模块，显示菜单，根据用户选择的菜单命令，执行相关操作。

|
|
|
|

|
|
|
|
|
|
## display_menu
|
|
|
|
|
|
