使用vector，创建Poker类，并创建出54张牌。随机分3个人的牌，每人17张。

首先，我们假设你需要创建一个扑克牌游戏中的`PokerCard`类，它包含卡的花色（Suit）和点数（Rank）。然后我们可以使用`std::vector`来存储所有牌，并将其分为三组代表三位玩家的牌。

#include <iostream>
#include <vector>
#include <random> // 需要随机库

// 定义扑克牌类
class PokerCard {
public:
    enum Rank {Ace = 1, Two, Three, Four, Five, Six, Seven, Eight, Nine, Ten, Jack, Queen, King};
    enum Suit {Hearts, Diamonds, Clubs, Spades};

    PokerCard(Rank rank, Suit suit) : rank(rank), suit(suit) {}

    // 显示牌的信息
    void display() const {
        switch (rank) {
            case Ace:
                std::cout << "A of ";
                break;
            default:
                std::cout << rank << " of ";
        }
        switch (suit) {
            case Hearts: std::cout << "Hearts"; break;
            case Diamonds: std::cout << "Diamonds"; break;
            case Clubs: std::cout << "Clubs"; break;
            case Spades: std::cout << "Spades"; break;
        }
        std::cout << "\n";
    }

private:
    Rank rank;
    Suit suit;
};

// 创建扑克牌容器并随机分配给玩家
int main() {
    const int total_cards = 52; // 一副扑克牌去掉大小王
    const int players = 3;
    const int cards_per_player = 17;

    std::vector<PokerCard> deck(total_cards);
    for (int i = 0; i < total_cards; ++i) {
        deck[i] = {static_cast<PokerCard::Rank>(i % 13 + 1), static_cast<PokerCard::Suit>((i / 13) % 4)};
    }

    std::random_device rd;
    std::mt19937 g(rd());
    std::shuffle(deck.begin(), deck.end(), g);

    std::vector<std::vector<PokerCard>> players_deck(players);
    for (size_t i = 0; i < players * cards_per_player; ++i) {
        players_deck[i / cards_per_player].push_back(deck[i]);
    }

    for (int player = 0; player < players; ++player) {
        std::cout << "Player " << player + 1 << ":\n";
        for (const auto& card : players_deck[player]) {
            card.display();
        }
        std::cout << "\n";
    }

    return 0;
}

在这个示例中，我们首先创建了一个52张牌的`deck`，然后通过随机排序将它们分配给三个玩家，每个人17张。每张牌都有一个`display()`函数来展示其花色和点数。
