求教。。在线等

你的文件是怎么做的

struct Book
{
    int num;    //保存的编号
    char bname[50];    //保存书名
    char writer[20];    //作者名
    char press[50];        //出版社
    char time[20];    //出版时间
    float price;
    struct Book * pNext;
};
book * download()  /*B要大写*/
{
    FILE *fp;
    book *head, *p1,*p2;
    p2 = NULL;
    head=p2;
    if ((fp = fopen("图书.txt", "a")) == NULL)
    {
        printf("File open error!\n");
        system("pause");
        exit(0);
    }
    while (!feof(fp))
    {
        p1 = (book *)malloc(sizeof(book));  /*B都要大写*/
        fscanf(fp, "%d %s %s %s %s %f\n", &p1->num, p1->bname, p1->writer, p1->press, p1->time, &p1->price);
        p2->pNext=p1;
        if (head == NULL)
            head=p2;
        p2=p1;   /*节点后移*/
        p1->pNext=NULL;
    }
    fclose(fp);
    return head;
}

谢谢。以后的Book会大写的。。昨天研究好了。
