C语言版-数据结构-期末课程设计-大作业（学生成绩管理系统）附源码+实验文档
在期末课程设计中，我完成了大作业——一个学生成绩管理系统，班级班级该系统涉及详细的管理管理inked源码设计和实现过程。首先，系统系统系统核心功能围绕学生信息管理，源码源码包括姓名、班级班级班级和学号，管理管理以及成绩查询、系统系统录入、源码源码修改和删除等操作。班级班级结构上，管理管理我使用了顺序表数据结构，系统系统影子淘客源码构建了包含插入、查找、删除和排序等模块的系统。
设计内容包括定义一个名为studentInformation的结构体，用于存储学生信息，包括各科成绩、总分等。洛克王国瞬移源码系统共设置了8个主要菜单：新建学生信息、插入学生、查询、删除、查询所有学生、按总分和学号排序、修改成绩以及退出。app网站制作源码例如，新建学生时，用户需要输入指定数量的学生信息，每名学生的信息包含姓名、班级、学号和各科成绩。
主函数通过预设的ht绘图软件源码账号密码（admin和root）进行登录，然后调用add_student、stu_check、del_stu等函数实现各个功能。add_student函数允许输入一定数量的学生数据，insert_stu函数确保学号唯一性，stu_check则根据学号查找学生信息。
排序功能采用冒泡排序，stu_num和sum_grade函数分别用于按学号和总分对学生信息进行排序。update_grade函数允许用户修改已有的学生科目成绩，如果输入的科目不存在则不作处理。
在使用说明部分，详细列出了每个操作的输入格式，如登录时需要输入admin和root，新建学生时需指定学生数量等。同时，也展示了部分操作界面示例，如登录成功、插入学生和修改成绩后的操作结果。
测试阶段，通过更改学生成绩并查看总分是否更新，验证了程序的正确性。然而，也发现了一些改进空间，比如当输入的学号前几位为0时，系统可能无法识别，以及在学生数量超过预设容量时，需要提示用户或调整存储策略。
