用C++编写一个教师和学生数据的输入和显示程序

#include<iostream.h>
#include<string.h>
class Student; //学生类
class Teacher; //教师类
class Person //人类
{
private:
int id;
char name[20];
public:
Person(int x,char *p)
{
id=x;
strcpy(name,p);
}
void show(Student s)
{
cout << "编号:" << id << endl;
cout << "姓名:" << name << endl;
cout << "班号:" << s.getclassid() << endl;
cout << "成绩:" << s.getscore() << endl;
}
void show(Teacher t) //show函数的重载
{
cout << "编号:" << id << endl;
cout << "姓名:" << name << endl;
cout << "职称:" << t.getzhicheng() << endl;
cout << "部门:" << t.getbumen() << endl;
}
};
