我在做一个链表操作的练习，做一个电话号码本，碰到这句读取字符串的语句，百思不得其解，怎么也弄不通，麻烦大家帮看看是错在哪里。谢谢！！！！！！

#include"STDIO.H"
#include"STDLIB.H"
#include"STRING.H"
#include"DEF_TYPE.H"

struct tel_node *Open_Node()
{
    FILE *fp_tel_node;
    struct tel_node *head;
    struct tel_node *read;
    struct tel_node *tail,*p_new;
    char temp;
   
    extern struct tel_node *Creat_Node();
    extern void Node_Display(struct tel_node *head);
   
    system("cls");
   
    fp_tel_node=fopen("E:\\电话号码本.txt","rt");
   
    if(fp_tel_node)
    {
        while(feof(fp_tel_node)==0)
        {
            fscanf(fp_tel_node,"%s\t%s\n",read->name,read->tel_code);
            printf("%s\t%s\n\n",read->name,read->tel_code);
            p_new=(struct tel_node *)malloc(sizeof(struct tel_node));
            strcpy(p_new->name,read->name);
            strcpy(p_new->tel_code,read->tel_code);
            p_new->next=NULL;
            if(head==NULL)
            {
                head=p_new;
            }
            else
            {
                tail->next=p_new;   
            }
            tail=p_new;
        }
        
        fclose(fp_tel_node);   
    }
    else
    {
        head=Creat_Node();
        Node_Display(head);
    }
   
    return(head);
}

就是fscanf(fp_tel_node,"%s\t%s\n",read->name,read->tel_code);那句

硬盘上的数据如下：

我的IDE缺少DEF_TYPE.H，无法调试。

缺“&”吗？

fscanf(fp_tel_node,"%s\t%s\n",read->name,read->tel_code);这句代码如果有错误，编译器会给出提示的，很不理解为什么不去看那个提示呢，“缺“&”吗？”是否要加 & 符号与read->name类型有关，从 strcpy(p_new->name,read->name);;这句代码来猜测，应该不用加，只有知道read->name类型的人才能给出准确的回答，

DEF_TYPE.H 如下

#ifndef _DEF_TYPE_H
#define _DEF_TYPE_H

struct tel_node
{
    char name[20];
    char tel_code[11];
    struct tel_node *next;
};

#endif

编译、链接都没有错误，一按打开键就弹出错误对话框，程序也再无法继续运行

我把程序全部发给你

“编译、链接都没有错误” ,不知道你的程序怎么能编译过，struct tel_node *Dec_Node(struct node*head,char *name) 看这句，明显类型错误

struct tel_node *Dec_Node(struct node*head,char *name)这句的确有错，但是我也不知道编译器是怎样通过的，用的是C-Free编译器，这个文件还没有调试到，调试到OPEN_NODE.C空

谢谢你那么仔细的帮我找错误，谢谢！！！！！！
