    menuprint();
    linklist *h;

    lnode *s=(lnode *)malloc(sizeof(lnode));
    h=(lnode *)malloc(sizeof(lnode));

    printf("请输入家电编号并且以#结束：");
    scanf(" %d",&s->jd.num);
    while(s->jd.num!='#')        //当x等于#时结束
    {
        s=(lnode *)malloc(sizeof(lnode));
        cout<<"请输入家电的单价："<<endl;

    }
    return h;

这只是我写的一部分，执行时出错，我不知道怎么改？？？、
