学生信息管理系统(C语言版)

Posted 2023-04-01

用C/C++编写的学生信息管理系统，最好有课程设计的论文，如果没有的话只有做好的系统也可以，代码要求50%以上注释！
最好是把整套完整系统的下载地址告诉我。万分感谢！！如果可以用的话，一定再追加50分！

源码分享C语言学生信息管理系统演示和说明（文件版）！

学生管理系统可以用来管理班级学生，能够对学生信息（包括姓名、性别、年龄、成绩等）进行增加、删除、更改、查询等操作。

该软件将学生信息保存在文件中，直接对文件中的数据进行增删改查操作，除了能够培养您的编程思维，还能让你深入了解文件操作。

软件运行后，首先会显示主菜单，让用户选择要进行的操作，如下图所示：

输入数字1~5，或者0，就可以进行相应的操作。例如输入数字1，就可以添加学生信息，如下所示：

添加成功后，会给出提示信息。

输入数字4，会显示子菜单，可以用来查询学生信息，如下图所示：

输入数字3，根据数学成绩来查询，如下图所示：

软件还会对用户输入的信息进行校验，不符合规则的数据会给出提示。例如，输入不合法的用户数据：
