반복자를 증가시키거나 감소시킵니다.

current_ 를 기본 반복자로 설정합니다.

1) 다음에 해당함 ++ current_ ; return * this ;
2) 다음에 해당함 ++ current_ ;
3) 다음 코드와 동일함 auto tmp = * this ; ++* this ; return tmp ;
4) 다음과 동일함 -- current_ ; return * this ;
5) 다음과 동일함 auto tmp = * this ; --* this ; return tmp ;
6) 다음에 해당함 current_ + = n ; return * this ;
7) 다음에 해당함: current_ - = n ; return * this ;

매개변수

n - 현재 위치 기준 상대 위치

반환값

1,4,6,7) * this
3,5) 변경 전에 생성된 * this 의 복사본
