아래 작성한 코드입니다.  환율 변수명 rate로 초기화 하고 그곳에 1500을 넣었습니다. 그리고 won 입력후 rate와 won을 곱하였는데 항상 "0"이 나옵니다.  교수님 도와주세요. (혼자 디버거를 찍어 보아도 won이라는 변수에 값이 입력되질 않습니다.)   #define _CRT_SECURE_NO_WARNINGS #include <stdio.h> int main() { int won = 0;  int dollar = 0; int rate = 0;    rate = 1500; printf("Input won\n"); scanf("won is %d\n", &won); dollar = won * rate; printf("Dollar is %d\n", dollar); return 0; }

시퀄라이즈 강의에서도 말씀하셧듯이,모델은 대문자, db는 소문자 뭐 이렇게 가르치셨는데 정확히 왜 이러는지 이유좀 알고싶습니다.   몽구스에도  ref: 'User'   module.exports = mongoose.model('Comment', commentSchema); 같이 스키마명은 소문자인데, 표현을 대문자 문자열로 하셨는데 왜 이러는거에요? 너무 햇갈려서 죽겠어요;;

[질문 내용]BookForm을 setter로 계속 값 넣어주신 부분에서 set, set, set.. 이게 너무 귀찮아서 구글링 해보니까 @Builder 어노테이션을 Lombok에서 지원하던데 BookForm 엔티티에 이거 사용해도 문제 없나요?   Book item = (Book) itemService.findOne(itemId);BookForm form = new BookForm.BookFormBuilder() .id(item.getId()) .author(item.getAuthor()) .isbn(item.getIsbn()) .name(item.getName()) .price(item.getPrice()) .stockQuantity(item.getStockQuantity()) .build();

useParams로 workspace 파라미터를 가져오려고 했는데 undefined가 떠서 SWR로 get 요청 시 undefined가 들어가 오류가 나는 상황입니다.   const Workspace: VFC = () => { const { workspace } = useParams<{ workspace: string; }>(); console.log(workspace, 'workspace'); <Switch> <Route path="/workspace/:workspace/channel/:channel" component={Channel} /> <Route path="/workspace/:workspace/dm/:id" component={DirectMessage} /> </Switch> workspace 컴포넌트 내부에서 라우팅할 때 주소값도 잘 설정했고 실제로 주소에도 잘 나오는데 useParams에서 왜 파라미터 값을 가져오지 못할까요?

  보시다시피 위의 isinf 함수 부분에서 오류가 발생하고 있는데 저 0.0 부분을 교수님이 한것처럼 변수에 대입하여 실행하면 정상적으로 실행되는데 왜 직접 대입하면 오류가 발생하는 것인지 궁금합니다.

userSchema.statics.findByToken   에서 왜 이거는 정적함수로 만드는건가요?   앞에 comparePassword, generateToken 메소드 만드는것과 왜 방법이 다른가요?

안녕하세요.   리팩토링 진행 이후 /images경로가 404이 뜨기 시작하면서 앱이 정상작동을 하지 않네요.   강의 내에서 리팩토링 진행하신 후에 앱을 테스트 하는 과정도 빠져있는 상황이라, 제가 잘못한건지, 아니면 강의 내용 자체에서 무언가 절차가 빠진건지 확실하지 않아서 강의를 여러번 따라해 봤지만 결과는 마찬가지였습니다.   나중에 고쳐지는 이슈인지, 아니면 제가 뭔갈 잘못 따라한건지 궁금합니다.   감사합니다.

Do not declare methods using ES6 arrow functions (=>). Arrow functions explicitly prevent binding this, so your method will not have access to the document and the above examples will not work. monggoose schema instance methods 작성시 화살표함수를 쓰게 되면 this는 무엇을 가르키나요

선생님 그렇다면 wday함수로 datetime을 추출했을 때 저는 숫자(1~7)로 나오는데 6과 7이 각각 토요일과 일요일이라고 생각하고 문제를 풀면 되나요?

수업에서 쓴 tf_hub 모델들이 mmdet 혹은 yolo보다 좋지 않은 성능을 보여주는데 tf_hub를 쓰는 이유가 있을까요? 아직 배우고 있는 중이라,,단순한 호기심에 여쭈어봅니다.   항상 좋은 수업 감사합니다:)

express로 웹 서버를 배운 후 기본기를 다지기 위해 강의를 보고 있습니다. 저는 시퀄라이즈를 쓰지 않고 mysql 모듈과 createConnection을 이용하여 DB에 연결을 하였습니다. 시퀄라이즈를 적용한 구문을 보면서 생각이 들었는데 실제 실무에서 SQL을 작성하기 보다(PreparedStatement와 관계없이) 시퀄라이즈를 사용하는 사례가 더 많을까요? 저 같은 경우에 로그인 체크 과정을 다음과 같은 방식으로 진행하였는데 가독성 측면에서 user.findOne이 낫다는 생각이 문득 들어 질문드립니다!

1. store action에서 try catch를 async 해주는 부분만 해주셨는데 loadComments 는 async 로 호출안하시고 loadPostsms async await으로 호출 하신 이유가 궁금합니다.     2. 보통 nuxt 프로젝트 실무에서 로그인, 로그아웃, 로그인 여부에 따른 redirect 이런 기능을 할 때  따로 쓰는 모듈?이 있나요?? 모듈을 써야 더 보안에 좋은지 따로 이점이 있는지 궁금합니다   답변 부탁드리겠습니다 ㅎㅎ

처음에는 Gradle설정이 안되다가 지금 Gradle 부분의 에러를 잡으니깐 메인 함수 부분이 아예 안돌아가고 springboot 함수가 인식이 안되는거 같습니다...아래 설정도 해놨고 해당 영상이랑 동일하게 설정했는데 뭐가 문제일까요... 인텔리제이도 두번이나 다시 깔았습니다..,            

./src/App.js Attempted import error: 'Switch' is not exported from 'react-router-dom'.라고 뜹니다. ㅠㅠ  무엇이 문제인지 계속 확인을 하고 있는데 계속 안됩니다. ㅠㅠ 

안녕하세요? 부트스트랩 강의 수강생입니다 프로젝트 2 Menu-1~2 강의 듣고 있는데요 app.scss로 작업 하시던데 정작 index.html에 href=적용할때는 app.css로 했을때만 적용되고 app.scss로 href= 하면 메뉴가 안보이는데 이유가 있을까요?.

큰 건 아닌데 문서에 오타가 있습니다.   max.java.lang.String = {0} 까지의 숫자를 허용합니다. 에러 문구가 문자인데 숫자로 표기되어있네요~   강의 너무 유익하고 잘 듣고 있습니다.~

강의보다가 어느순간 로그인페이지 프론트엔드가 생겨서 그런데요. 혹시 어느부분부터 프론트 연동에 대한 강의가 있는건가요?

안녕하세요, 항상 강의 잘 듣고 있습니다.   querydsl을 이용하여 view를 활용하여 select할 수 있는 방법이 있을까요?  

안녕하세요 :)   현재 To Do App 관련 실습을 하고 있는데, 영상과 똑같이 코드를 작성했는데도 계속 네비게이션 바 색상 변경이 안 되서 질문을 남깁니다. ㅠㅠ   그리고 스토리보드에서 embed in으로 네비게이션 컨트롤러를 넣고 실행을 하면 선생님의 실행화면에서는 네비게이션 바 부분의 색깔이 바 아래 부분과 구분이 되는데, 저는 실행하면 구분이 안 되고 모두 하얀색으로 나오는데 이유가 궁금합니다 !
