双向链表建立出错……高手指点一下
程序代码:
struct Node { int Data; struct Node *prior; struct Node *next; }Node,*Linklist; Linklist create(Linklist p) { Linklist head,p,q; int x; head =(Node *)malloc(sizeof(Node)); head->prior = NULL; head->next = NULL; q=head; scanf("%d",&x); while(x!=0) { p=(Node *)malloc(sizeof(Node)); p->Data=x; p->prior=q; p->next=NULL; q->next=p; q=p; scanf("%d",&x); } q->next=NULL; return head; }
