C语言实现---学生成绩管理系统

C语言实现了学生成绩管理系统,可以进行学生成绩的增加,删除,更新,查询,计算和展示. 完整代码如下: #include<stdio.h> #include<stdlib.h> #include<string.h> typedef struct person //定义结构体 { char num[10]; //学号 char name[20]; //姓名 float cyuyan; //C语言成绩 float en; //物理学成绩 float ji; //原子物理成绩

Java编写学生成绩管理系统

思路:定义两个类,一个scoreinformation类,一个scoremanagement类,scoreinformation类用于编写姓名,学号,以及各项成绩的输入函数,scoreinformation类有七个私有变量,和各个变量的get(),set()函数,scoremanagement类用于表现各项功能,包括学生信息的引入函数,学生信息的添加函数,学生信息的修改函数,学生成绩绩点的计算函数,以及退出系统的函数,在最后的主函数中,首先调用存储学生信息的函数,然后运用switch,case函
