Помогите упростить код

2 игрока, каждый тянет 1 карту по очереди, колода 36карт + 2 джокера .с 6 по 10 за карту 1 очко, в-2,д-3,к-4,т-10,дж20.если у какого то игрока сумма очков больше 20 то вывести победителя

вот код, можно помочь сделать ее без классов? то есть просто for и массивы, rand

class Game

string players[2] = { "1", "2" };

}

if (this->players_score[0] > 20)
{

}
else if (this->players_score[1] > 20)

}
}
};

int main()
