내 C 코드에서 Segmentation Fault 오류를 수정하는 방법

Question

게임 Mancala 코드를 작성하고 테스트하는 중입니다. 지금까지, 나는라는 오류가 무엇입니까 :

분할 오류 (코어 덤프)

을 나는 그것을 수정하고 계속 실행하는 방법을 모르겠어요.

Answer 1

더 작은 조각으로 코드를 분리하고 각 조각을 테스트하고 싶을 수도 있습니다. 또는 아마도 이것은 당신을 도울 수 있습니다 : http://ericlippert.com/2014/03/05/how-to-debug-small-programs/

&을 scanf에 넣으려면 올바른 제안이라고 생각합니다.

어쨌든, 이것은 또한 이상한 :

이

while (position!=6 || position!=7 || position!=8 || position!=9 || position!=10 || position!=11) 
{ 
      scanf("%d",&position); 
} 

당신이 위의 무엇을 기대합니까? 그것은 항상 그 루프를 입력하고 위치가 6이면 7 일 수 없으므로 나오지 않습니다. 따라서 OR 문으로 인해 참이됩니다.
