这是一个创建二叉树的程序 麻烦大家帮我改一下错误，最好把关键处标出来 谢谢

帮你改了不下10处错别字，。代码肯定不是你写的

	struct node *lc,*rc; 
}Bitree;                    //这里少;

 Bitree *create_bt() 
{ 
	Bitree *root =(Bitree *)malloc(sizeof(Bitree));          //分配存储空间 
	Bitree *p,*s[20];              //s[i]应该是指针，照你后面的用法
	TelmType x; 
	int i,j; 
	printf("i,x"); 
	scanf("%d,%c",&i,&x); 
	while(i!=0&&x!='#') 
	{ 
		p=(Bitree *)malloc(sizeof(Bitree)); 
		p->date=x;                //p=data=x;全是错别字
		p->lc=NULL; 
		p->rc=NULL; 
		s[i]=p;               //p是指针

发现1楼对于指针问题特别感兴趣 ，每次一有这个类型 就出现

[jn989]

1楼辛苦了，lz以后要仔细的呀，问题解决了，飘过……呵呵
