进制转换

int transfer_num(int y, int ml, int* buff)
{
    int i,j,temp,cnt;
    temp = ml;
    buff[0] = 0;

    for ( i=1;;i++ )
    {
        if (temp!=0)
        {
            buff[i] = temp%y;
            buff[0]++;
        }
        else
            break;
        temp = temp/y;
    }

    return buff[0];
}

//25 = 11001

//buff = 10011

// 使用时需注意。
