안녕하세요...너무 너무 훌륭한 강의에 감탄하고 강사님의 모든 과정을 다 수강하려고 생각하고 있는 교육생입니다. 어쩜 이렇게 귀에 쏙쏙 들어오게 잘 얘기해주시는지... 현재는 맘만 급해서 여러 개 신청하고 왔다갔다 하며 듣고 있지만 완강하도록 하겠습니다. 다름이 아니오라 템플릿 엔진에 대해 궁금한 게 있어 문의 드립니다. 처음에 몰랐을 때는 (지금도 잘 모르지만) 막연하게 tiles같은 화면 레이아웃을 관리하는 프레임워크인 줄 알았는데 지금은 느낌이 약간 jsp와 비슷한 역할을 하는게 아닌가 하는 생각이 들고 thymeleaf에서 사용하는 fragment도 약간 jsp의 include와 비슷한 역할을 하는게 아닌가 하는 생각이 드는데 제가 맞게 이해 한 걸까요? thymeleaf에도 tiles같은 레이아웃을 관리하는 기능이 있는지요? 또한 제가 백엔드 구성하면서 화면단을 tiles를 쓰려고 했었는데 너무 old하다는 핀잔만 들었습니다. 참고로 저희는 아직 boot는 쓰지 않고 있구요... tiles는 정말 old한 기술이고 많이 사용하지 않는 기술인거예요? 궁금해서 질문드립니다.

4.9 Printf() 함수가 인자들을 해석하는 과정에서 질문있습니다.

미해결

홍정모의 따라하며 배우는 C언어

안녕하세요. Printf 함수가 인자들을 해석하는 과정 관련해서 질문있습니다. 교수님께서 설명해주신 내용은 이해했습니다. 다만, float과 double 모두 메모리에 스택으로 저장되는 과정에서 원래 4바이트인 float이 8바이트로, 원래 8바이트인 double이 8바이트로 변환되어 저장되게 되는데, 그렇다면 float의 경우 8바이트 중 실제 사용되는(값이 저장되는 공간) 공간은 4바이트 뿐이니, 4바이트는 낭비된다고 생각해야 되나요? 아니면, 원래 값은 4바이트 크기로 저장되나, 변환과정에서 4바이트가 8바이트를 모두 사용되도록 내부에 저장되는 값까지 변환되는 것인가요? 만약 전자(8바이트 중 앞의 4바이트만 사용)라면, 메모리의 float이 사용하는 공간을 제외한 뒤에 있는 4바이트에 다른 값을 저장하더라도 실제로는 아무런 문제가 없게 될것 같아서요. 감사합니다.

아나콘다 파이썬 패키지 설치 오류 질문드립니다.

미해결

아나콘다에서 파이썬 환경설정 할수 있게 블로그 보고 따라하는 중인데요 똑같이 따라 헀는데 계속 오류 떠요 아무리 찾아봐도 비전공자라 잘모르겠네요 ㅠㅠ Anaconda Prompt (anaconda3) 실행화면 블로그 캡쳐 사진입니다. 이건 제화면인데 똑같이 따라했는데 저렇게 오류가 뜨는데 해결법좀 부탁드리겠습니다. 어제부터 퇴근하면 이거랑 씨름중입니다 ㅠ0ㅠ
