c++ - 编译器通过将数组传输到函数给我一个错误

Question

我自己学习 c++ 并阅读此链接上的教程：https ://www.learncpp.com 在我的练习中，我必须从数组库中编写一个数组并用卡片填充它。在我填满它之后，我必须显示所有带有 std::cout 的卡片。

但是，当我将数组传输到 main.cpp 中的函数 printCard 时，我得到了一个我无法解决的错误。

在下面你可以看到我的整个程序。谢谢您的帮助

甲板.h

#include<array>
enum CardRank {

    RANK_2,
    RANK_3,
    RANK_4,
    RANK_5,
    RANK_6,
    RANK_7,
    RANK_8,
    RANK_9,
    RANK_10,
    RANK_JACK,
    RANK_QUEEN,
    RANK_KING,
    RANK_ACE,

    MAX_RANK

};

enum CardSuit {

    SUIT_HEART,
    SUIT_CLUBS,
    SUIT_SPARE,
    SUIT_DIAMONDS,

    MAX_SUIT
};

struct Card {

    CardRank rank;
    CardSuit suit;

};

void printCard(Card card);
std::array<Card, 52> createDeck();
void printDeck(std::array<Card, 52>* deck);
