我需要一个功能来洗牌我创建的卡片和一个 环形 在打印改组值的主要中。我不想改变 任何事物 否则。该功能必须将52张卡和甲板尺寸摄取为 参数。有帮助吗？我的问题是我不知道如何编写洗牌功能并打印它。

#include <iostream>
#include <string>
#include <cstdlib>
#include <ctime>
using namespace std;
class Card
{
private:
    string suit;
    string value;
public:
     Card() = default;
    Card(string a, string b)
    {
        value = a;
        suit = b;
    }
    string getSuit()
    {
        return suit;
    }
    string getValue()
    {
        return value;
    }
    void print()
    {
        cout << getValue() << " of " << getSuit() << endl;
    }
    void shuffle(Card cardlist[52], int size)
    {
    }
};
int main()
{

    Card cardlist[52];
    cardlist[0] = Card("2","Spades");
    cardlist[1] = Card("3","Spades");
    cardlist[2] = Card("4","Spades");
    cardlist[3] = Card("5","Spades");
    cardlist[4] = Card("6","Spades");
    cardlist[5] = Card("7","Spades");

    cardlist[7] = Card("9","Spades");
    cardlist[8] = Card("10","Spades");
    cardlist[9] = Card("Jack","Spades");
    cardlist[10] = Card("Queen","Spades");
    cardlist[11] = Card("King","Spades");
    cardlist[12] = Card("Ace","Spades");
    cardlist[13] = Card("2","Hearts");
    cardlist[14] = Card("3","Hearts");
    cardlist[15] = Card("4","Hearts");
    cardlist[16] = Card("5","Hearts");
    cardlist[17] = Card("6","Hearts");
    cardlist[18] = Card("7","Hearts");
    cardlist[19] = Card("8","Hearts");
    cardlist[20] = Card("9","Hearts");
    cardlist[21] = Card("10","Hearts");
    cardlist[22] = Card("Jack","Hearts");
    cardlist[23] = Card("Queen","Hearts");
    cardlist[24] = Card("King","Hearts");
    cardlist[25] = Card("Ace","Hearts");
    cardlist[26] = Card("2","Diamonds");
    cardlist[27] = Card("3","Diamonds");
    cardlist[28] = Card("4","Diamonds");
    cardlist[29] = Card("5","Diamonds");
    cardlist[30] = Card("6","Diamonds");
    cardlist[31] = Card("7","Diamonds");
    cardlist[32] = Card("8","Diamonds");
    cardlist[33] = Card("9","Diamonds");

    cardlist[50] = Card("King","Clubs");
    cardlist[51] = Card("Ace","Clubs");
    for (int i = 0; i < 52; i++)

我通常不帮助完成作业，除非它是一个衬里。你很幸运，因为那是！(但是，您的教授不太可能在没有解释的情况下接受这一点，因此您需要花一些时间理解为什么这有效。(

要使用shuffle的卡片：

shuffle(begin(cardlist), end(cardlist), mt19937(random_device()()))

实时示例

我还应该在这里指出您在Card类中有一个shuffle方法。这是没有意义的。方法可以在对象上操作。每个Card都是一个独特的扑克牌，可以通过其方法来操作其属性。你不会把黑桃的王牌洗牌。您洗牌一张牌。因此，如果您要创建一个包含52个Card对象的Deck类，那么制作Deck::shuffle方法是很有意义的，因为您实际上确实会随机洗牌。

您可以使用rand()函数随机生成两个数字，然后将这两个数字作为其索引交换。

添加一个for循环可以使您更随机进行改组。

void shuffle(Card cardlist[52], int size)
{
    int v2;
    int v1;
    int loop=rand() % 100;
    for(int i=0;i<loop;i++)
        {   v1 = rand() % size;
            v2 = rand() % size;
            Card temp=cardlist[v1];
            cardlist[v1]=cardlist[v2];
            cardlist[v2]=temp;
    }

请注意，这是假设您需要洗牌功能作为类卡的成员

最好使其成为班级卡的朋友。
