编程题2_数据和教师学生类

1、名称编程题2_数据及教师学生类备注描述题目描述：有五个类，各类的主要数据成员见下方说明，请自己定义合理的成员函数，编程实现体现该继承 关系的程序，并定义教师对象、学生对象、研究生对象、在职研究生对象，输出他们的信息。关于数据成员：数据类Data :成员name 保存姓名；/该类是Teacher类和Student类的基类教师类Teacher :增加成员sal保存工资；学生类Student :增加成员id保存学号； 该类是PostGrad 类的基类研究生类PostGrad :增加成员dn保存系别；教师中的在职研究生类 Tpost ：不另外定义数据成员。该类有两个直接基类：Teacher类和研 究生

2、类PostGrad关于成员函数：每个类中均定义输出所有数据成员的函数void print ()。具体代码可参考主函数及对应的输出结果样例来完成。主函数代码如下：int main ()Teacher tobj("Zhuhong”, 2000);Student sobj("Wanghui", "B05030417");PostGrad pobj("Lixuefeng", "Yj040217", "Computer Department");Tposttpobj("Liuling&

3、quot;, "Yz040318", "Society Department", 800);cout << "the teacher:n"tobj.print ();cout << "nthe student:n"sobj.print ();cout << "nthe postgraduate:n"pobj.print ();cout << "nthe teacher and postgraduate:n"tpobj.print

4、 ();return 0;提示：(1)最前面需要作相应的文件包含(2)请注意类之间的继承关系，可能存在虚基类在保存并预览之后，点 开：“测试用例”选项 卡，再选择卜方的“添 加”，加入两组测试测试用例，无输入部分： 输出部分：the teacher: Name:Zhuhong sal=2000the student: Name:Wanghuiid=B05030417the postgraduate: Name:Lixuefeng id=Yj040217 dn=Computer Departmentthe teacher and postgraduate: Name:Liuling sal=80
