#include<stdio.h> #include<stdlib.h> typedef struct BiTNode{ char data; struct BiTNode *lchild; struct BiTNode *rchild; }BiTNode,*Bintree; void CreateBinaryTree(Bintree *T){ char ch; scanf("%c",&ch); if(ch=='#') *T==NULL; else{ *T = (Bintree)malloc(sizeof(BiTNode)); (*T)->data = ch; CreateBinaryTree(&(*T)->lchild); CreateBinaryTree(&(*T)->rchild); } } void midOrder(Bintree T){ if(T){ midOrder(T->lchild); printf("%c",T->data); midOrder(T->rchild); } } int main() { Bintree T; CreateBinaryTree(&T); midOrder(T); return 0; }修改这段代码

代码中存在一个明显的错误，即第11行应该是赋值操作而不是等于操作。此外，函数名`midOrder`应该改为`inOrder`，以符合中序遍历的命名规范。修改后的代码如下：

#include <stdio.h>
#include <stdlib.h>

typedef struct BiTNode{
    char data;
    struct BiTNode *lchild;
    struct BiTNode *rchild;
} BiTNode, *Bintree;

void CreateBinaryTree(Bintree *T){
    char ch;
    scanf("%c", &ch);
    if (ch == '#')
        *T = NULL;
    else{
        *T = (Bintree)malloc(sizeof(BiTNode));
        (*T)->data = ch;
        CreateBinaryTree(&((*T)->lchild));
        CreateBinaryTree(&((*T)->rchild));
    }
}

void inOrder(Bintree T){
    if (T){
        inOrder(T->lchild);
        printf("%c", T->data);
        inOrder(T->rchild);
    }
}

int main(){
    Bintree T;
    CreateBinaryTree(&T);
    inOrder(T);
    return 0;
}
