关于在c ++中改组数组的快速问题

出于某些原因，我的牌在我洗牌之前有正确的数字和套装。在我做完之后......卡片上的所有数值都变为1，套装消失了......最奇怪的事情。

任何帮助都会很棒！

// ViewController.swift

let loginOperation = LogInOperation(
                         mail: "mail@example.com", 
                         password: "123123", 
                         completion: { op in
                             // parsedObject would be the user's info 
                             print(op.parsedObject?)
                         }, error: { error in 
                             print(error.localizedDescription)
                         }
                     )
OperationQueue.addOperation(loginOperation)

一些输出

const int Deck::RANKS[13] = {2,3,4,5,6,7,8,9,10,11,12,13,14};
const char Deck::SUITS[4] = {'H','D','C','S'};
Card cards[52];
int cardNum = 0;


Deck::Deck() : size(0)
{
    cardNum = 0;
    for (int i = 0; i < 13; i++)
    {
        for (int j = 0; j < 4; j++)
        {
            cards[size] = Card(RANKS[i],SUITS[j]);
            cout << "Card Created with " << RANKS[i] << " and " << SUITS[j] << "\n";
            size++;
        }
    }

    shuffle();

    for(int x = 0; x < 52; x++)
    {
        Card c = cards[x];
        cout << "Card Contains " << c.value << " and " << c.suit << "\n";
    }

}

Deck::~Deck() {}

void Deck::shuffle()
{

    size = MAX_SIZE;
    std::random_shuffle(begin(cards), end(cards));
}

//关闭后

Card Created with 13 and C
Card Created with 13 and S
Card Created with 14 and H
Card Created with 14 and D
Card Created with 14 and C
Card Created with 14 and S

Card.cpp

Card Contains 1 and 
Card Contains 1 and 
Card Contains 1 and 
Card Contains 1 and

错误在这里。您正在为自己分配参数。

Card::Card(int value, char suit)
{
    value = value;
    suit = suit;
}

您可以使用此关键字

Card::Card(int value, char suit)
{
    this->value = value;
    this->suit = suit;
}

但是要做的就是使用评论中所述的列表初始化。
