Packet Generator 4 강의까지 수강했습니다. 이전 3강에서 Skill 구조체 내에 Attribute 리스트가 들어 있는 형태로 패킷을 생성했었는데요, 생성은 정상적으로 되는데 List<Attribute> attributes = new List<Attribute>(); 식으로 선언하다보니 구조체 내에서 동적 할당이 안 된다는 문제가 발생합니다. 이런 경우는 구조체 내 리스트를 처리하기 위한 포맷을 따로 만들어야 하나요? 아니면 공통적으로 Read/Write에서 리스트를 동적 할당해도 괜찮을까요?

재밌고 유익한 강의감사합니다. 저는 여기저기다양한 홈페이지에서 공부하고있습니다. 다른 홈페이지에서는 var는이제더이상 사용하지않는다고 하는데요 저는 강의 거의 70퍼센트까지 수강했습니다 var를 그냥 let으로만 바꾸면 상관없는건가요? let으로바꿀시에는 달라지는것이 있을까요?  아님 이런식으로 문법작성하는것에 의의를 둬야하나요? 그리고 이 강의를 다수강하고나서 어떤식으로 연습을해야하는지도 여쭤봅니다 친절한답변감사합니다!

안녕하세요 선생님~ 강의를 열심히 따라하고 있으나 프로젝트 생성시 파일명이 빨간색으로 여럿 뜨며, welcome 페이지가 404 오류가 납니다 ㅠㅠ 

인프런 이메일 : nukkong@gmail.com깃헙 아이디 :  nerdnuzzi@gmail.com깃헙 Username : nerdnuzzi 부탁드립니다. 감사합니다.

아래와 같이 쓰게 되면 .box .box-inner . box-title 로 css 파일에서 보여지는데... .box { .box-inner { .box-inner-title { } } } &를 쓰게 되면  css 파일에서  클래스 안에 속한 것이 아니라 단독으로 .box-inner-title 로 보여집니다. &를 쓸 때에도 .box .box-inner .box-inner-title 로 보여지게 할 순 없나요? .box { &-inner { &-title { } } }

안녕하세요. 수업을 보면서 따라하는 도중에 이 부분에서 CKEditor를 넣어주면 Postdetail 를 가져오려고 누르면 계속 에러가 뜨는데 어떻게 해야할지몰라서 이렇게 질문드립니다. Errors 감사하구 강의 잘보고 따라가고 있습니다.

12강까지는 무리없이 잘 실행이 되었는데... 로그인시 토큰이 없다고 나옵니다. 혹시나 뭔가 실수가 있나해서 몇번씩 강좌를 다시 확인했는데도 똑같은 결과가 나옵니다.ㅠㅠ 왜일까요?

int i = 1; while (i <= 10) { printf ("hello world %d", ++i); } 로 작성했을 때, %d 부분이 2 부터 11로 출력되는데 왜 그런 건가요? 조건이 i <= 10 니까 11은 안 나와야 하는 거 아닌가요?

우분투에서 별도로 flask를 설치하지 않아도 기존 소스를 가져와 실행하는데 문제되지 않는 걸까요?

삭제된 글입니다

setCachePeriod 메소드에 20으로 설정했다면 브라우저(client) 편 컴퓨터 캐시에 해당 리소스가 20초간 유지되고, 그 후에는 다시 해당 리소스를 요청해서 응답코드가 200이 된다는 건가요? 이것이 아니라면 전후의 차이가 정확히 무엇인지 다시한번 자세한 설명 좀 부탁드립니다..

안녕하세요. 좋은 강의 감사하게 잘 보고있습니다. MemoryMemberRepository에서 Member를 리턴하는 이유가 있는지 궁금합니다. store에 저장만하면 save()의 기능은 끝나는거 아닌가요? 굳이 member를 리턴하는건 왜 그런건가요??

안녕하세요, 강의듣는중 궁금한것이 있어서 질문드립니다. 1) 프롬프트상 바벨로 에러없이 변환 성공했을때, 항상 구버전 브라우저(IE11등)에서 동작하는것을 보장해주나요? ( 휴먼 코드 에러같은 것을 제외하고 ) 2) 1)번과 동일선상에 질문입니다. JQuery, Vue, React의 라이브러리(Component)들을 사용하다보면, 버전업 되면서 점점 "IE11는 더이상 지원 안함"이라고 되어있더라고요,  이런것도 바벨을 돌려서 IE11에서 돌아가게 할 수 있나요??

선생님께선 bottom-up방식이셨네요... 전 처음에풀때 top-down방식으로 한번 해보았습니다. 혹시 이런방식도 가능한지 여쭤보고싶습니다~ def DFS(x,y): if x == n-1: if a[x][y] == 2: print(sp) return else: cnt = 0 a[x][y] = 0 // 갈림길 조정 - 만약에 아래로뻗는 방향밖에없다면 그대로 좌우아래 검색, 만약 아래랑 좌우중 한개가 같이있을경우 무조건 좌우만 검색하게끔 for j in range(3): tx = x+dx[j] ty = y+dy[j] if 0<=tx<n and 0<=ty<n and (a[tx][ty] == 1 or a[tx][ty] == 2): cnt += 1 if cnt == 1: loop = 3 else: loop = 2 for j in range(loop): tx = x+dx[j] ty = y+dy[j] if 0<=tx<n and 0<=ty<n and (a[tx][ty] == 1 or a[tx][ty] == 2): DFS(tx, ty) a[tx][ty] = 1 for z in a: print(z) print() n = 10 a = [ [1,0,1,0,0,1,0,1,0,1], [1,0,1,1,1,1,0,1,0,1], [1,0,1,0,0,1,0,1,0,1], [1,0,1,0,0,1,0,1,1,1], [1,0,1,0,0,1,0,1,0,1], [1,0,1,1,1,1,0,1,0,1], [1,0,1,0,0,1,0,1,1,1], [1,1,1,0,0,1,0,1,0,1], [1,0,1,0,0,1,1,1,0,1], [1,0,1,0,0,2,0,1,0,1] ] dx = [0, 0, 1] dy = [1, -1, 0] sp = 0 for i in range(len(a[0])): if a[0][i] == 1: sp = i print(sp) a[0][i] = 0 DFS(0,i)

굳이 파일을 만들어서 관리하는 이유가 있나요??

선생님 cmd 창과 주피터에서 두번 설치 했더니 이미 설치가 완료 되었다고 뜨고 실행은 안됩니다. 아나콘다도 시도해 보았는데 환경문제로 설치 fail 했다고 뜨네요 어떻게 하면 좋을까요?

파일 업로드 강의 따라하고 있는데요 DROP ZONE에서 파일 첨부 하기 하면 이미지 파일이 첨부가 안됩니다. 그리고 터이널에 아래와 같은 오류가 뜨네요 [HPM] Error occurred while trying to proxy request /api/product/image from localhost:3000 to http://localhost:5000 (ECONNREFUSED) (https://nodejs.org/api/errors.html#errors_common_system_errors) 혹시 왜 그럴까요?ㅠㅠ
