홍정모의 따라하며 배우는 C언어
그냥 변수명을 int true = 1, false = 0; 이라고 지어서 printf("True is %d\n",true); printf("False is %d\n", false); 이렇게 출력하는거랑 똑같지 않나요? 왜 사람들이 bool타입을 만들어서 사용하는건가요?

홍정모의 따라하며 배우는 C언어
본 강의에서 사용된 fabs() 말인데요. fabs()를 사용하지 않고 그냥 while ((guess - PI) > 0.01)이라고 코드를 짜면 왜 제대로 돌아가지 않는건가요? guess도 PI도 다 double로 선언되어 있으니까 두 변수를 뺀 값도 double 타입을 가져서 소수점 자리수가 상세하게 저장되지 않나요? 그래서 (guess - PI) > 0.001이 제대로 계산될 줄 알았는데, fabs를 사용하지 않으면 결과값이 제대로 출력되지 않네요...?

면접과 취업을 부르는 '퍼블리셔 개인 포트폴리오 홈페이지' 제작
안녕하세요 선생님, 개인 포트폴리오 홈페이지를 포함해서 반응형 웹 사이트 작업물들에 대한 HTML, CSS 유효성 검사도 하나씩 다 해야 하나요? 초반에 몇 번 검사를 해서 img태그의 alt속성 오류 및 h태그 중복 등 오류가 많이 떠서 일일이 고쳤었지만, 양이 방대해서 중단했습니다. 개인 홈페이지 제작 중 웹 접근성, 웹 표준을 지킨다는 문장을 넣으려다 보니 괜히 마음에 조금 거슬리네요..
