int main()
{
    double s,j;
    int i,q,g;
    char*a[]={"壹","贰","叁","肆","伍","陆","柒","捌","玖"};
    char*b[]={"元","拾","佰","仟","萬","拾","佰","仟","亿"};
    char*d[]={"角","分"};
    for( ; ; )
    {        
        printf("此程序用于实现大小写的转换\n您输入阿拉伯数字,我们将为您转换为汉字\n请输入阿拉伯数字：\n");
        scanf("%lf",&s);
        i=12;
        for(q=i-1;q>=0;q--)
        {
            j=s/pow(10,q);
            g=(int)j%10;
            if(g!=0)
                printf("%s%s",a[g-1],b[q]);
        }
        for(q=-1;q>=-2;q--)
        {
             j=s/pow(10,q);
            g=(int)j%10;
                if(g!=0)
                    printf("%s%s",a[g-1],d[-q-1]);
            }
        printf("\n\n");
    }
}

这里的代码有问题
for(q=-1;q>=-2;q--)
        {
             j=s/pow(10,q);
            g=(int)j%10;
                if(g!=0)
                    printf("%s%s",a[g-1],d[-q-1]);
            }

什么问题？求指点！
