这段代码是一个二叉树的基本操作实现。以下是对应的补充代码：
typedef struct BiTNode{ElemType data;struct BiTNode *lchild, *rchild;}BiTNode, *BiTree;void CreateBiTree(BiTree &T){char ch;scanf("%c", &ch);if (ch == '#')T = NULL;else{T = (BiTree)malloc(sizeof(BiTNode));T->data = ch;CreateBiTree(T->lchild);CreateBiTree(T->rchild);}}void PreOrderTraverse(BiTree T){if (T){printf("%c ", T->data);PreOrderTraverse(T->lchild);PreOrderTraverse(T->rchild);}}void InOrderTraverse(BiTree T){if (T){InOrderTraverse(T->lchild);printf("%c ", T->data);InOrderTraverse(T->rchild);}}void PostOrderTraverse(BiTree T){if (T){PostOrderTraverse(T->lchild);PostOrderTraverse(T->rchild);printf("%c ", T->data);}}int BTDepth(BiTree T){if (T == NULL)return 0;int leftDepth = BTDepth(T->lchild);int rightDepth = BTDepth(T->rchild);return leftDepth > rightDepth ? leftDepth + 1 : rightDepth + 1;}void Leaf(BiTree T){if (T != NULL){if (T->lchild == NULL && T->rchild == NULL)LEAFCOUNT++;Leaf(T->lchild);Leaf(T->rchild);}}void NodeCount(BiTree T){if (T != NULL){NODECOUNT++;NodeCount(T->lchild);NodeCount(T->rchild);}}
此外，还需要注意在main()函数中对应的调用和输入处理。
