基类：

#include<iostream>
#include<string>
using namespace std;
class Person \\声明基类person
{
public:
	Person() = default;  \\默认构造函数

    \\带参构造函数
	Person(string Number, string Name) :number(Number), name(Name)
	{
		cout << "The contructor of base class Person is called." << endl;
	}

	void show()
	{
		cout << "The person's number:" << number << endl;
		cout << "The person's name:" << name << endl;
	}
	~Person() = default;  \\默认析构函数
protected:                \\基类的保护数据成员
	string number;  \\编号
	string name;  \\姓名
};

学生类：

\\声明基类person的公用派生类student学生类
class Student :public Person
{
public:
	Student() = default;  \\默认构造函数
    \\带参构造函数，在其初始化列表中调用基类的构造函数
	Student(string Number, string Name, string Cnumber, float Result) :Person(Number, Name), cnumber(Cnumber), result(Result)
	{
		cout << "The constructor of derived class Student is classed." << endl;
	}
	void stushow()
	{
		cout << "学生的学号：" << number << endl;
		cout << "学生的姓名：" << name << endl;
		cout << "学生的班号：" << cnumber << endl;
		cout << "学生的成绩：" << result << endl;
	}

protected:
	string cnumber;  \\班号
	float result;  \\成绩
};

教师类：

\\声明基类person的公用派生类teacher教师类
class Teacher :public Person
{
public:
	Teacher() = default;  \\默认构造函数
    \\带参构造函数，在其初始化列表中调用基类的构造函数
	Teacher(string Number, string Name, string Title, string Section) :Person(Number, Name), title(Title), section(Section)
	{
		cout << "The constructor of derived class Student is classed." << endl;
	}

	void Teashow()
	{
		cout << "老师的编号：" << number << endl;
		cout << "老师的姓名：" << name << endl;
		cout << "老师的职称：" << title << endl;
		cout << "老师所属的部门：" << section << endl;
    }
protected:
	string title; \\职称
	string section;  \\部门
};

主函数：

int main()
{
	Student stu("000001", "张三", "01", 98);
	stu.stushow();  \\显示学生信息
	Teacher tea("000001", "李四", "教授", "人工智能");
	tea.Teashow();  \\显示教师信息
	system("pause");
	return 0;
}

程序运行结果如下：
