求助！问题：文件输出最后一个重复输出和第一个不输出
这是一个结构数组写的简单地手机通讯录，它的问题是执行浏览操作的时候，会把最后一组数据重复输出。但是把浏览操作中 while(!feof(fp))
{
fscanf(fp,"%s%s%s%s%s%s%s%s",g.name,g.age,g.tele,g.qq,g.weixin,g.bd,g.email,g.sex);
printf("%s%4s%15s%11s%11s%9s%18s%4s\n",g.name,g.age,g.tele,g.qq,g.weixin,g.bd,g.email,g.sex);
}
的 while(!feof(fp))换成while( fscanf(fp,"%s%s%s%s%s%s%s%s",g.name,g.age,g.tele,g.qq,g.weixin,g.bd,g.email,g.sex)！=E0F)时会丢掉第一组数据，求帮助！
