while(!feof(fp))

printf("\t2.主编：%s\n",Book[i].writer);
printf("\t3.出版社：%s\n",Book[i].press);
printf("\t4.出版年：%s\n",Book[i].year);
printf("\t5.版次：%s\n",Book[i].edition);
printf("\t6.ISBN书号： %s\n",Book[i].isbn);
printf("\t7.定价：%d\n",Book[i].price);
printf("\t8.拥有本数：%d\n",Book[i].all);
printf("\t9.借出本数：%d\n",Book[i].borrow);
printf("\t10.现余本数：%d\n\n",Book[i].now);
}
}
}
程序执行这段时跳不出循环，while(!feof(fp))不是文件指针到达末尾时就会跳出循环了吗，fread函数在for里面判断时是会被执行一次的吗？
