資料結構中typedef struct node用法

typedef struct node
{
	elemtype data;
	struct node* lchild, * rchild;
}binode,*bitree;
           

等價于

typedef struct node
{
	elemtype data;
	struct node* lchild, * rchild;
};
typedef struct node binode;
typedef struct node* bitree;
           

即讓binode等價于node

bitree 等價于node*
