1. 결과화면이 제가 원하는대로 안나오는데..
첨부파일 참조해주세요 ..
첨부 1 에서는 빨간색으로 표시한 부분에 43이라고 떠야되는데 안뜹니다.
첨부 2 에서는 중간중간에 한줄 씩 빈 라인이 있는데 없애고 싶습니다.
이 문제를 해결하려면 소스코드를 어떻게 고쳐야 되는지 알고 싶습니다.
2.FreeFormatFile 을 수정한다면
.과 빈라인 처리를 어떻게 해야되는지 알고 싶습니다.
3.Symtab 도 file로 저장을 하고 싶은데 어떻게 해야되나요?
위 세가지 사항에 대해 구체적으로 알려주세요 ㅜㅜ
어떤 코드를 어디에 추가해야하는지, 어떤 코드를 고쳐야하는지 알려주세요!
고수님들 부탁드립니다!
