}궁금증 해결하기
void startBattle(Player player, Monster& monster)
여기서 왜 Player player는 포인터고 Monster& monster는 레퍼런스야?
🔺 2. Monster* monster (포인터)로 넘길 경우
startBattle(player, &slime) 처럼 슬라임의 주소(포인터)를 넘겨도 원본을 때릴 수 있어서 정답이야! 하지만 포인터를 쓰면 함수 안에서 monster->getHp() 처럼 화살표(->)를 써야 하고, 혹시라도 빈 주소(nullptr)가 넘어올까 봐 불안해져.
✅ 3. Monster& monster (레퍼런스)로 넘길 경우 (C++의 꽃!)
&를 붙이면 복사본을 만들지 않고 "원본 몬스터에 또 다른 별명표만 하나 딱 붙여서" 함수로 넘겨줘.
복사도 안 하니까 빠르고, 포인터처럼 화살표(->) 대신 점(.)을 그대로 쓸 수 있어서(monster.getHp()) 코드도 훨씬 깔끔해져! C++ 창시자가 "일반 변수의 원본을 함수로 넘길 때는 웬만하면 포인터 대신 참조자(&)를 쓰세요!"라고 권장하기도 했어.
