c++学校人员信息管理系统.docx

1、c+学校人员信息管理系统1.C+课程设计题目:学校人员信息管理系统用c+设计一个大学教师和学生管理程序,教师包括编号(a),(c),职称(d)和教研室数据(b)的数据输入输出; 大学生包括编号(m),( s),性别(t),班号(n),英语(e),高等数学(f)和数据结构(g)三门课程成绩输入输出和计算机平均分(ave);研究生包括编号,性别,班号,指导教师和研究方法数据输入输出; 博士后数据的输入输出;博士后既是教师也是研究生.(用派生,继承的方法可以做)2.功能如下图所示： 3.部分代码#include#include#includepersons.h#includestudent.h#in
