题  目	学生成绩管理系统
主要 内容	用C语言开发一个简单的学生成绩管理系统。实现学生信息管理，并且有界面和跳转。 【数据结构】 1．学生成绩信息。包括：学号，姓名，成绩。 2．登陆账号信息。包括：密码、 权限级别（区别系统管理员用户和普通用户）。 3．学生个人信息。包括：学号，姓名，性别，学院，专业，联系方式。 【系统实现功能】 1.系统登陆   使用登陆账号和密码登陆，判断用户编号和密码是否一致，正确，则根据角色不同显示不同的界面。管理员显示管理员菜单。普通用户显示普通用户界面。 2.系统管理员 （1）学生信息管理：学生信息和成绩的增、删、改、查功能。 （2）全部展示所有学生的信息和成绩在一个交互界面上。 3. 普通用户（学生） （1）学生可以注册自己的个人信息。 （2）学生可以根据自己的学号查询自己的个人信息和成绩。
任务 要求	一、提交材料应包括： （1）系统源代码 （2）课程报告 二、整个设计过程具体要求 （1）需求分析 要求学生对案例系统进行分析，设计出需要完成的功能，完善各个模块的调用关系；要有系统结构图 （2）设计过程 要求学生进一步明确各模块调用关系，进一步完善模块函数细节（函数名、参数、返回值等），至少有一个关键模块的流程图。 （3）实现过程 要求学生养成良好的编码习惯、完成各个模块并进行测试，最终完成系统整体测试； （4）总结阶段 按照要求完成系统设计和实现报告，并进行总结。

一、需求分析

学生基本信息和学生学分信息动态化绑定，管理员与学生操作相结合的学生信息管理系统，与此同时丰富了一些界面的跳转和防止用户错误输入的提醒。

二、概要设计

总览流程图，如图1-1所示，进入首页后，可以选择进入管理员界面或者学生操作界面。进入管理员界面后，可以选择所有学生的数据或者对他们的数据进行增删查改。进入学生操作界面后，可以选择学生登录和学生注册。

图1-1 总流程图

管理员展示流程图，如图2-1所示，进入管理员界面后，可以显示所有学生的学分表和信息表，也可以对他们的数据进行增加，删除，修改，查询的操作。

图2-1 管理员流程图

学生界面流程图，如图3-1所示，进入学生界面，可以选择学生登录或者注册，如果你登录没有注册的学号信息的话，会跳转到注册页面去完成相应的注册操作。

四、调试分析

从主界面到管理员界面或者学生界面使用Easy-x坐标定位来进行调试，再到之后的显示学生信息和学分全揽，发现是空白，什么都没有，所以推测是输入的问题，也可能是文件的问题。于是找到对应模块进行调试，进入管理员界面内的录入学生信息和学生注册，发现录入学生信息显示录入学生已满，所以现在数据已经达到了最大容量值了，但为什么还是写不上去。于是我打开文件，看了一下有42行空白，有字节数，说明是写进去了，但是没有完全将有用的数据写入，而且还有无用的数据写入，于是将对应模块的代码断点逐行调试，发现是变量nowstudentsnum的问题，基于这个问题，写了两个函数来控制认识的变化，每次需要看人数时，调用UseStudentNumber函数，用完之后，人数增加或者减少，再用SaveStudentNumber函数，来控制变量的范围，于是改了之后代码达到了预期的效果。

五、测试结果

从主界面能顺利跳转到（第一个按钮）管理员界面或者（第二个按钮）学生界面，如图1-1，进入管理员界面需要输入密码，如图1-2。

图1-1 首界面

图1-2 管理员登录密码

进入管理员界面，可以正常跳转到管理员界面，如图2-1.在管理员界面，（第一个按钮）到查看所有学生的个人信息表和学分信息表，如图2-2和2-3。（第二个按钮）可以到对学生数据进行操作（增加，删除，查找，修改），并且将操作后的数据存储到文件中。

图2-1 管理员界面

图2-2 学生学分全揽

图2-3 学生信息全揽

  进入修改，添加学生数据界面，如图3-1。有对应的4个按钮，有录入学生信息（第一个按钮），如图3-2。删除学生信息（第二个按钮），如图3-3。查找学生信息（第三个按钮），如图3-4。修改学生信息（第四个按钮），如图3-5，将学生数据进行对应的操作后可以将对应信息储存到相应的文件中。

图3-1 管理员操作全揽

图3-2 录入操作

图3-3 删除操作

图3-4 查询操作

图3-5 修改操作

进入学生界面，如图4-1。可以跳转到（第一个按钮）学生登录界面，如图4-2。或者可以跳转到（第二个按钮）学生注册界面，如图4-3。也可以点击页面返回回溯到首页面，如图4-4。进入对应的页面进行可以进行学生登录或者注册，完成流程后的同时可以直接将学生信息（如图4-5），学生学分（如图4-6），学生人数（如图4-7）直接写入文件中

图4-1 同学界面

图4-2 登录界面

图4-3 注册界面

图4-4 主界面

图4-5 学生信息存储文件

图4-6 学生学分存储文件

图4-7 学生人数存储文件

六、课程心得总结

通过完成这个学生管理系统的创作，从开始的界面，到中间的页面之间的跳转，我从学习Easy-x的函数到逐步掌握，通过写这个学生管理系统也是见证了我代码能力的成长，逐渐熟练掌握调试，断点，检查代码错误，文件的存储，页面的变换，按钮的设计，通过这次学生管理系统的创作，也是助推我代码能力的成长助推器，也愿在以后的代码求学路上，我仍能保持初心，一直走下去。
