(1)编写一个学生和教师相关数据输入和显示程序。设计三个类 person, student 和 teacher 类，其中 student 和 teacher 是由 person 类派生出来的。学生（student）数据有学号、姓名、性别、年龄、班级号和期末三门功课总分；教师(teacher)数据有职工号、姓名、性别、年龄、职称和系别。在主程序中，定义两个学生和两个教师，从键盘输入他们相关的数据，并将输入数据输出显示在屏幕上。（提示：person 类有两个公有成员函数：void input();输入学生或教师的姓名、性别和年龄；显示输出函数 void display()；显示学生和教师的姓名、性别和年龄。该类中有三个私有数据成员：姓名 char name[20]、性别和年龄。Person 类定义已经给出，请设计其他两个类和主函数。 class Person { char name[20]; char gender; int age; public: Person() {} Person(char* Name,char Gender,char Age) { cout<<"Constructing "<
代码如下，如有帮助，请采纳一下，谢谢。
