本系统是程序设计与问题求解课程设计项目，实现了库存零件 CSV 格式数据文件的读取和保存，以及数据的增删改查（CRUD）、排序和图表显示等功能。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。

## 关于零件库存管理系统

```
## 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（menu），选择菜单命令（menu1）、确认（confirm）、退出（exit）等子模块。
数据处理模块包括读取数据（read_data）、保存数据（saveData）、打印数据（show_goods）、查询数据（find_goods）、添加数据（insert）、更新数据（increase_count）、删除数据（delete_from_list）、数据排序（sort）和图表（Show）等子模块。其中查询、添加、更新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。
![系统模块图](images/main.drawio.svg)
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。
#### init
系统初始化。
#### display_menu
显示菜单命令。
## 详细设计
针对概要设计
#### main
Step 1: 初始化
Step 2: 根据用户选择的命令执行对应的操作
Step 2.1: 显示菜单
Step 2.2: 选择菜单命令 c
Step 2.3: if c == CMD_READ then 读取数据
Step 2.4: if c == CMD_SAVE then 保存数据
Step 2.5: if c == CMD_PRINT then 打印数据
Step 2.6:

#### savedata
Step 1: 输入文件名
Step 2: 打开文件
Step 3: if 打开文件失败 then 提示打开文件失败并结束
Step 4: 将所有库存记录写入文件
Step 5: 关闭文件
![保存数据流程图](graph/saveData.drawio.svg)
#### insert
Step 1: if 数据库满 then 提示数据库满并结束
Step 2: 输入零件编号
Step 3: if 零件已存在 then 提示零件已存在并结束
Step 4: 输入零件名和库存数量
Step 5: 添加新零件到数据
Step 6: 提示添加成功
![添加库存记录流程图](graph/insert.drawio.svg)
#### show_goods
Step 1: 创建表格边框
Step 2: 如果没有商品
Step 3: 提示“数据库内没有商品”
Step 4: 输入编号
Step 5: 打印商品
![打印数据流程图](graph/show_goods.drawio.svg)
#### readData
Step 1: if数据库空则返回“读取数据失败”
Step 2: if没有商品则返回“注意：您的数据库内没有商品信息”
Step 3: 输入文件名称
Step 4: 输出数据库里的商品信息
