질문 제목 : input 파일에 빈줄때문에 ㄷㄷinput 파일에 있는 데이터를 이용하여 계산하는 건데요
중간에 스페이스 한칸 때문에 계속 에러가 나와요

이거고요

input file이
square 14.5
rectangle 14.5 4.65
circle 14.5
cube 13
prism 1 2 3

spheres 2.4
cylinder 1.23
cylinder 50 1.23
triangle 1.2 3.2

입니다... 보시다시피 prism 과 spheres 사이에 빈칸때문에 에러가 나요
이것만 없애면 잘되는데 말이죠
무엇이 잘못 된 것일까요?
