안녕하세요!
예전에 한번 소스 올렸는데 개판이라고 해주신 소스 다시올려요...ㅠ
어정쩡한 실력에 갑자기 덜커덩 프로젝트 맡아서 몇일째 c언어랑 c++책 참고해가면서 하고있는데..
문과에서 공대로 편입한데다가 처음이라 그런지 여간 힘든게 하나둘이 아니네요...ㅠㅠ

제가 알고있는 if문은...
if다음에 else if해서 문장넣어주고
마지막으로 else 하는거랑 복잡한거는 {}묶어주는거.... 이것만 알고있는데...
이론으로만 알고있는걸 실제 해보니 힘드네요...

이부분은...
1~9을 입력해서 값을 받으면 그에맞는걸 출력해주고 처음으로 돌아가시겠냐는 질문이 반드시 나와야 하고
y와 n도 그에맞는 조건에 맞도록 설계되어져야 하는데 그이외의 값을 입력하면
잘못입력했다고 다시입력하도록 창 보여주게 만드는 그런부분인데요...
if랑 else if else넣어도 오류가 계속 나고....
if문안에 처음으로 돌아가시겠습니까 (y/n)을 입력하려해도 어떻게 넣어야 할지 모르겠어요..ㅠ

어디서부터 틀린건지...
부족한게 무엇인지좀 조언해주시면 정말 감사하겠습니다..
