里面有很多的例子

creatlist()
{    int cycle=1;
	llist *p,*s,*r;
	r=head=(llist *)malloc(sizeof(llist));
	clrscr();
	p=head;
	while(cycle)
	{
		scanf("%d",&r->data);
		if(r->data!=0)
		{
			s=(llist *)malloc(sizeof(llist));
			s->data=r->data;
			p->next=s;
			s->pro=p;
			p=s;
		}
		else cycle=0;
	}
        head=head->next;
        head->pro=NULL;
	   p->next=NULL;
}
