 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。

+## 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。
+
+
