请教关于建立二叉树程序（c语言的）

来源：百度知道 编辑：UC知道 时间：2024/06/07 08:47:25
#include<stdio.h>
#include<malloc.h>
typedef struct
{
char data;
struct node *lchild,*rchild;
}Tree;

void Init(Tree *t)
{
char ch;
printf("input a char:\n");
scanf("%c",&ch);

if(ch=='#')t=NULL;
if(ch=='%')return;
else
{
t=(Tree*)malloc(sizeof(Tree));
t->data=ch;
Init(t->lchild);
Init(t->rchild);
}
}

void Xbl(Tree *t)
{
while(t)
{
printf("%c",t->data);
Xbl(t->lchild);
Xbl(t->rchild);
}
}

main()
{
Tree t;
Init(&t);
Xbl(&t);
getch();
}
老是死循环，哪里有问题，请帮忙改一下
