C语言在读取文件的时候多读取了最后一行。导致数据总是多了一个0，求助解决方案

Question

由于总代码长度过长，显示部分代码块。

/*将文件内的内容读入到链表中*/

struct worker_link *pNew;

struct worker_link *pTail = NULL;

char eat = ' ';

while (!feof(fp1))

{

pNew = (struct worker_link *)malloc(sizeof(struct worker_link));

if(pNew == NULL)

{

printf("Error!");

exit(-1);

}

fscanf(fp1, "%s%c%s%c%c%c%d%c%s%c%s%c", pNew->work_num, &eat, pNew->name, &eat, &pNew->sex, &eat, &pNew->position_num, &eat, pNew->birthday, &eat, pNew->add, &eat);

if(pHead == NULL)

pHead = pNew;

else

pTail->pNext = pNew;

pTail = pNew;

}

pTail->pNext = NULL; //链表结尾要把尾指针的pNext指针置空

p = pHead;

fclose(fp1);

问题出在这里：while (!feof(fp1))前没有读取文件的语句，feof(fp1)要在逻辑上跟在读语句之后才能正确判断，你还没有读文件，判断什么结束没有不就多出一行了？改法很多，最简单的是把while (!feof(fp1))改成while (1)，在fscanf语句后面加一句加一句if(feof(fp1)) break;。
