C++언어 연습문제32

[문제]

아래의 실행결과와 main함수를 참고하여 Person class와 UnivStudent class를 정의하라.

조건1) UnivStudent 는 유도 클래스로, Person은 기초 클래스로 정의하라.
조건2) 동적 할당을 사용하라.

int main(void)
{
	UnivStudent ust1("Kim", "Mathematics");
	ust1.WhoAreYou();

	UnivStudent ust2("Yoon", "Physics");
	ust2.WhoAreYou();

	return 0;
}

 

[실행결과]

My name is Kim
My major is Mathematics

My name is Hong
My major is Physics

 

[코드]

#include<iostream>
using namespace std;

class Person
{
private:
	char* name;
public:
	Person(const char* myname)
	{
		name = new char[strlen(myname) + 1];
		strcpy(name, myname);
	}
	~Person()
	{
		delete[]name;
	}
	void WhatYourName()	const
	{
		cout << "My name is " << name << endl;

public:
	UnivStudent(const char* myname, const char* mymajor)
		:Person(myname)
	{
		major = new char[strlen(mymajor) + 1];
		strcpy(major, mymajor);
	}
	~UnivStudent()
	{
		delete[]major;
	}
	void WhoAreYou()	const
	{
		WhatYourName();
		cout << "My major is " << major << endl << endl;
	}
};


int main(void)
{
	UnivStudent ust1("Kim", "Mathematics");
	ust1.WhoAreYou();

	UnivStudent ust2("Yoon", "Physics");
	ust2.WhoAreYou();

	return 0;
}
