+# 学生成绩管理系统
 
+2023年4月23日
+ 王振宇 李文菲 武杭凯 李培毅
+
+## 项目简介
+
+本学生成绩管理系统是为教师提供管理班级成绩的工具，该系统可以实现的对学生的成绩进行增，信息导入等基本功能，以及对学生成绩排序和分段的扩展功能，有利于对学生成绩管理。
+下载地址：https://bdgit.educoder.net/p2i3t8vuh/text4.git
+项目开发过程中采用 Kanban  (看板)进行任务管理和分工协作，并使用 Git 对程序代码和文档进行版本管理。任务分工情况如下：
+
+|任务 |设计 |开发 |测试 |文档 |
+|-----|-----|-----|-----|-----|

+
+## 关于学生成绩管理系统
+
+设计一个学生成绩管理系统，要求采用命令行菜单界面进行交互，具备读取、查询、修改、插入、删除和排序等基本功能，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：
+数据的读取、保存、打印、查询、修改、插入、删除、排序和图表展示。
+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
+
+分析系统的功能需求和界面需求，编制用户手册如下
+
+ #### C1启动程序
+
+命令行中执行命令 ./app ，系统启动，显示提示信息，然后显示功能菜单，等待用户输入命令
+~~~
+库存管理系统启动
+| 1 录入 | 2 计算 | 0 退出 
+请选择： 
+~~~                 
+
+ #### C2: 显示命令菜单
+
+~~~
+| 1 录入 | 2 计算 | 0 退出 
+请选择：
+~~~
+#### C3: 退出程序
+
+选择菜单命令 0 ，退出程序
+~~~
+请选择：0
+程序退出
+~~~
+#### C4：添加学生成绩
+~~~
+请选择：1
+输入学生序号：1
+输入学科序号：4
+输入成绩：100
+学生1成绩 已添加
+| 1 录入 | 2 计算 | 0 退出 
+
+请选择： 1
+输入学生序号：1
+输入学科序号：4
+学生成绩已存在
+~~~
+#### C5：计算每个学生各门课程的总分和平均分
+~~~
+请选择：2
+输出序号：1
+输出各门课程的总分：4，100
+输出各门课程的平均分：4，100
+~~~
+
+## 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。
+数据处理模块包括数据输入(ReadScore)，数据计算(AverSumofEveryStudent)等模块组成。
+上述各模块通过主程序（main）进行调用，系统模块图如下。
+![](流程图.png)
+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
+![](text.drawio.svg)
+
+
+#####add_data
+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 学生成绩已存在 then 提示学生成绩已存在并结束
+Step 4: 输入学生名和学科
+Step 5: 添加新成绩到数据
+Step 6: 提示添加成功
