책에 나온 p39~41의 SLL을  보기만 해서는 안될 것같아 함수부분 이라도 직접짜보려고 하는데;;

왠지 모르게 책에 나온 코드는 에러가 안뜨는데;

제가 짜니까 에러가 뜨네요..  코드도 거의 일치하는데 왜 그런지 모르겟어요..

코드 좀 봐주시겠어요?

//void SLL_InsertNewHead()이 함수는 복잡할 것 같아 일부러 뺐어요.

여기서
linkedlist.c(68) : error C2275: Node : illegal use of this type as an expression
1>        c:\users\김형준\documents\visual studio 2008\projects\make_sll\make_sll\linkedlist.h(13) : see declaration of Node

이런 오류가 뜨면서 Node*관련 ㅊCurrent변수 같은 것들이 undeclared identifier로 인식을 못하더군요..

왜 그런건지 쿨럭;;

부디 코드가 좀 길더라도~~ 답변부탁드려요  ㅇ-ㅇ..
