继承与派生实验

定义一个本科生类Undergraduate，包括学号、姓名、专业这三个数据成员，在此基础上派生出研究类Graduate，并增加导师、发表论文数等属性，可以通过显示个人信息函数ShowInfo来查个人档案。

#include<iostream>

#include<string>

using  namespace  std;

class  Undergraduate

{

public:

	int id;

	string name;

	string profession;

  
	
	void  ShowInfo()

	{

		cout <<  "Name:"  << name << endl;

		cout <<  "ID:"  << id << endl;

		cout <<  "profession:"  << profession << endl;

	}

};

class  Graduate : public  Undergraduate

{

public:

	int id;

	string name;

	string profession;

	string tutor;

	int essay_num;

  

	void  ShowInfo()

	{

	cout <<  "Name:"  << name << endl;

	cout <<  "ID:"  << id << endl;

	cout <<  "profession:"  << profession << endl;

	cout <<  "tutor:"  << tutor << endl;

	cout <<  "Essay Number:"  << essay_num << endl;

	}

};

void  test01()

{

	Undergraduate u1;

	u1.name="LiJiayan";

	u1.id=2019070918;

	u1.profession="digital information";

	Graduate g1;

	g1.name="ZhangBo";

	g1.id=1991;

	g1.profession="software engineering";

	g1.tutor="LiJiayan";

	g1.essay_num=100;

	u1.ShowInfo();

	g1.ShowInfo();
}
int  main()

{

	test01();

	return  0;

}

输出结果：

加油吧！
