用C++编写相关程序1

Question

实验内容：
1、编写一个学生和教师数据输入和显示程序，学生数据有编号，姓名，班级和成绩，教师数据有编号，姓名，职称和部门。要求将编号，姓名输入和显示设计成一个类person，并作为学生数据操作类student和教师数据操作类teacher的基类。
2、合理设计student类、 teacher类以及主函数，完成输入多个学生和教师的信息并显示。

下面的代码是通过重载输入输出符来实现的，也可通过函数的方式。

#include <iostream>
#include <string>
using namespace std;

class person
{
public:
    string id;
    string name;
public:
    friend istream& operator >>(istream& is,person &p)
    {
        is >> p.id >> p.name;
        return is;
    }
    friend ostream& operator <<(ostream& os,person& p)
    {
        os << "id:" << p.id << ",name:" << p.name;
        return os;
    }
};


class Student:public person
{
public:
    int grade; //班级
    float score;//成绩
public:
    friend istream& operator >>(istream& is,Student& stu)
    {
        is >> stu.id >> stu.name >> stu.grade >> stu.score;
        return is;
    }
    friend ostream& operator <<(ostream& os,Student& stu)
    {
        os << "id:" << stu.id << ",name:" << stu.name << ",grade:" << stu.grade << ",score:" << stu.score;
        return os;
    }
};

class teacher :public person
{
public:
    string pro; //职称
    string partment; //部门
public:
    friend istream& operator >>(istream& is,teacher& t)
    {
        is >> t.id >> t.name >> t.pro >> t.partment;
        return is;
    }
    friend ostream& operator <<(ostream& os,teacher& t)
    {
        os << "id:" << t.id << ",name:" << t.name << ",pro:" << t.pro << ",partment:" << t.partment;
        return os;
    }
};


int main()
{
    Student s1, s2;
    teacher t1, t2;
    cout << "请输入学生1的编号、姓名、班级和成绩：";
    cin >> s1;
    cout << "学生1的信息如下：";
    cout << s1 << endl;

    cout << "请输入学生2的编号、姓名、班级和成绩：";
    cin >> s2;
    cout << "学生2的信息如下：";
    cout << s2 << endl;

    cout << "请输入教师1的编号、姓名、职称和部门：";
    cin >> t1;
    cout << "教师1的信息如下：";
    cout << t1 << endl;

    cout << "请输入教师2的编号、姓名、职称和部门：";
    cin >> t2;
    cout << "教师1的信息如下：";
    cout << t2 << endl;
    return 0;
}
