关于重定义，各位大虾帮一下，先谢谢了

//#include "c9-7.h"

typedef int KeyType;
struct ElemType
{
        KeyType key;
        int others;
};

typedef ElemType TElemType;
typedef struct BiTNode
{
        TElemType data;
        BiTNode *lchild,*rchild;
}BiTNode,*BiTree;
void InitBiTree(BiTree &T);
void DestroyBiTree(BiTree &T);
void InOrderTraverse(BiTree &T,void(*Visit)(TElemType));
#define InitDSTable InitBiTree
#define DestroyDSTable DestroyBiTree
#define TraverseDSTable InOrderTraverse
BiTree SearchBST(BiTree T,KeyType key);

〉〉typedef ElemType TElemType;
typedef struct ElemType TElemType;
〉〉BiTNode *lchild,*rchild;
struct BiTNode *lchild,*rchild;

风格如此的不统一。
