学生成绩管理系统C++语言
学生成绩管理系统
广东海洋大学 本科生课程设计
 说明:本《学生成绩管理系统》程序是一个具有对学生信息进行录入、添加、删除、根据学号进行学生

信息的查询、显示已有学生信息的显示、对学生成绩进行统计(包括最高分,最低分,及格率和需要补

考的学生),可以对已有的学生信息进行修改,保存和读取输入的数据等功能。一切功能都可以在运行

的软件中运行。

有些偏向于 C 了
C++ 写管理系统还是比较建议用面向对象的思维

回复 楼主 lyb661
哈哈,看了半天,最后才看到你的主程序,这个不是好主意。
书上说,主程序最好放前面,以便一目了然。
你这个是千呼万唤才出来,最后才知道你要干什么,和c++说什么oop有点不搭。
虽然我还没编一个程序,连课本的程序都还没开始敲,但你这么写感觉有点象做流水账。
