Can someone help me plz



{
        Tuple row;
        UInt32 null_index = 0;
        UInt32 re_count = 0;
        for (auto i = 0U; i < number_columns; i++)
        {
            if (bitmap[i])
                re_count++;
        }
        re_count = (re_count + 7) / 8;
        boost::dynamic_bitset<> columns_null_set;
        readBitmap(payload, columns_null_set, re_count);
        for (auto i = 0U; i < number_columns; i++)
        {
            UInt32 field_len = 0;
            
            if (!bitmap[i])
                continue;
