求助，不知道为什么char[]不能通过%s输出。可能是指针问题？

[jin349620491]

在下学生，这是我的一个作业。要求读取Input.txt，处理内容，排序筛选并写入Output.txt。我采用了二叉树的结构。问题与这个树有关。
以下是代码：

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

typedef struct TreeNode *PtrToNode;
typedef PtrToNode Tree;
 
struct TreeNode
{
	char name[9];
    int age;
    int networth;
    Tree Left;
    Tree Right;
};

Tree GetContent(char str[21])
{
    Tree temp;
	temp = (Tree)malloc(sizeof(struct TreeNode));
	int n = strlen(str) - 1;
    int i;
    int count = 0;
    char Age[4];
    char Networth[8];
    for(i = 0; i < n; i++)
    {
		if(str[i] != ' ')
        {
			temp->name[i] = str[i];
            printf("temp->name[%d] = %c\n",i,temp->name[i]);//********************for testing
            system("pause");
        }
        else{break;}
    }
    temp->name[i] = '\0';
    printf("temp->name[%d] = %c\n",i,temp->name[i]);//********************for testing
    system("pause");
    printf("temp->name = %s\n",i, temp->name);//********************for testing
    system("pause");
    for(++i; i < n; i++)
    {

        else{break;}
    }

第一行的两个数字分别为源数据的行数和对源数据的处理参数。暂且不提，问题出在第37行左右。树中有个name[9]成员。用来提取Input.txt从第二行到第十三行的人名。调试时注意到，读入第二行的时候，name[0]='Z', name[1]='o', name[2]='e'......name[7]='l', name[8]='\0'。但是紧接着的printf("temp->name = %s\n",i, temp->name);却输出了一大堆乱码。甚至因为没有找到末尾而直接导致程序崩溃。这让我很是摸不着头脑。难道它不是一个字符串数组？还是因为有个temp->的缘故让它不符合%s的定义了？求解。
（Ps：在下的电脑出了点问题，VC不能用，然后用的啊哈C进行编程。但啊哈C并不提供调试功能，所以可能有些其实很显眼的地方没能看到。）
（再Ps：在下的C语言功底并不很深厚，很多东西都是自己瞎琢磨的，如果各位大侠发现有什么地方不对的或者不好的，请不吝指出，多谢！）

没看懂。。。

[勤奋的小游侠]

printf("temp->name = %s\n",i, temp->name); 楼上的确实说对了，为什么人的代码还有个i在里面？是copy进没有改好吧

[xionggch]

printf("temp->name = %s\n",i, temp->name);//********************for testing 少了 i 对应的输出格式，变成成%s和i对应了所以乱码

[xwuno1]

printf("temp->name = %s\n",i, temp->name)中缺少了一个控制符哈

i...........
