二叉数组的基本操作

//二叉数组的输出
void DisBTree(BTNode* bt)
{
	if(bt)
	{
		DisBTree(bt->lchild);	
		DisBTree(bt->rchild);
		printf("%c    ""\n",bt->data); 
	}
}

//二叉数组的高度
int BTHeight(BTNode *bt)
{
	int lchilddep,rchilddep;
	if(bt == NULL) 
		return 0;     //递归终止条件
	else
	{
		lchilddep = BTHeight(bt->lchild);
		rchilddep = BTHeight(bt->rchild);
		return (lchilddep>rchilddep)?(lchilddep+1):(rchilddep+1);
	}
}

//二叉数的结点个数
int NodeCount(BTNode *bt)
{
	int num1,num2;   //用来存放返回的值
	if(bt == NULL)
		return 0;
	else
	{
		num1 = NodeCount(bt->lchild);
		num2 = NodeCount(bt->rchild);
		return (num1+num2+1);
	}
}

//二叉树的叶子结点数
int LeafCount(BTNode *bt)
{
	int num1,num2;
	if(bt == NULL) 
		return 0;
	else if(bt->lchild==NULL&&bt->rchild==NULL)
		return 1;
	else
	{
		num1 = LeafCount(bt->lchild);
		num2 = LeafCount(bt->rchild);
		return num1+num2;
	}
}
