** 디폴트 매개변수 값은 선언부에만 작성 가능, 구현부에만 디폴트 값을 작성하면 컴파일 오류 발생
[왜?] 함수 콜 이전에 매개변수 값을 호출부에서 미리 세팅해야 하기 때문에
** 부분적 디폴트 값
디폴트 매개변수는 반드시 오른쪽부터 순차적으로 정의 필요
만약, 오른쪽부터 채우지 않으면, 컴파일 오류가 발생
[왜?] 함수 호출시 인자는 왼쪽에서 오른쪽으로 순차적으로 채워지기 때문
즉, 매개변수는 항상 왼쪽부터 채워지므로,
디폴트 값이 적용될 수 있는 비어있는 부분은 반드시 오른쪽부터 존재해야 한다
[만약 중간 매개변수만 디폴트 값을 지정한다면?]
컴파일러가 어떤 값을 디폴트 값으로 대체해야 할 지 모호해지므로 오류가 발생

* 참조자는
선언과 동시에 누군가를 반드시 참조해야 함 → 즉, NULL로 초기화 불가능!!
변수에 또다른 이름을 붙여주는 것이 목적이기 때문에 상수를 대상으로 참조자를 선언할 수 없다!!
