열혈 C++ 프로그래밍 5-1 문제

/*

문제 4-3의 문제 2를 통해서 NameCard 클래스를 정의하였다.

그런데 이 클래스도 생성자 내에서 메모리 공간을 동적 할당하기 때문에 복사생성자가 필요한 클래스이다

이에 복사생성자를 적절히 정의해보기 바라며, 복사 이후에 문제가 발생하지 않음을 다음 main 함수를 통해서 확인하길 바란다

int main(void)

{

        NameCard manClerk("Lee", "ABCEng", "010-1111-2222", COMP_POS::CLERK);

        NameCard copy1 = manClerk;

        NameCard manSENIOR("Hong", "OrangeEng", "010-3333-4444", COMP_POS::SENIOR);

        NameCard copy2 = manSENIOR;

        copy1.ShowNameCardInfo();

        copy2.ShowNameCardInfo();

        return 0;

}
