关于找一下代码的问题在哪里！(语言-c语言)

#include<stdio.h>#include<stdlib.h>typedef struct node{ int data; struct node* left; struct node* right; }Node;typedef struct tree{ struct node* root;}Tree;char insert(Tree tree,char value){ if(value==NULL) return; else{ Node node=malloc(sizeof(node)); node->data=value; node->left=insert(node->left,value); node->right=insert(node->right,value);} return value;}int get_hight(Node *node){ int max; if(node==NULL) { return 0; } else { int left_h=get_hight(node->left); int right_h=get_hight(node->right); int max=left_h; if(right_h>left_h) { max=right_h; } } max=max+1; printf("%d",max); return max;}int count=0;int countleaf(Node *node,int count){ if(node==NULL) { return; } if(node!=NULL&&node->left==NULL&&node->right==NULL) { count++; } if(node!=NULL) { countleaf(node->left,count); countleaf(node->right,count); } return count;}int main(){ Node *node=NULL; Tree *tree=node; int i,j=0; char a[15]={'A','B','D',' ',' ',' ','C','E',' ','G',' ',' ','F',' ',' '}; for(i=0;i<15;i++) { insert(node,a[i]); printf("%c",a[i]); } countleaf(node,j); printf("%d",j); get_hight(node);} "#left")

将代码源码粘贴下，图片不好验证啊~

请使用插入代码块功能
