C 访问违规读取位置0xcccccccccccccccccccc和卡对象

错误似乎与指针有关，但我无法完全指出正在发生的事情。我将稍后将卡数组分成类型和西装，但是现在我想弄清楚错误的情况，我尝试制作交换指针的参数，没有真正的成功。我非常感谢任何帮助。

    b = temp;
}

{
    randomizer();
    int random = rand() % 52;
    cout << "Your draw is: " << card[random] << endl;
    return card[random];
}
void Deck::randomize(string arr[], int size)
{
    randomizer();
    for (int i = size - 1; i > 0; i--)
    {
        int j = rand() % (i + 1);
        swap(arr[i], arr[j]);
    }
