关于#c++#的问题：随机分布几张扑克牌在3行，让玩家选中一个牌，告诉程序这个牌在哪行，3次后程序判断出是哪张扑克牌在别处看到的代码，但是我个人有很多地方没看明白：（个人是初学者

是一个小游戏，随机分布几张扑克牌在3行，让玩家选中一个牌，告诉程序这个牌在哪行，3次后程序判断出是哪张扑克牌
在别处看到的代码，运行后结果完全没问题，但是我个人有很多地方没看明白：（个人是初学者，看不懂代码，见谅！）
如图，有时这个扑克牌是没法对齐的，我试过把空格变成“\t”也不行，这个要怎么对齐？

然后就是具体流程，比如三维数组那里，抱歉我个人真的没看懂，有人能帮忙详细讲解下吗
代码如下：

#include
#include
#include
using namespace std;

void pai(int a)
{
    int i, j;
    i = a / 13;           //让i为0~4的数，j为0~12的数；
    j = a % 13;              //i用来判断花色(a/b/c/d)，j用来判断数字和字母；
    if (j != 9 && i< 4)      //
    {
        cout << "   ";
    }
    switch (i)
    {
    case 0:
        cout << "a-";
        break;

    case 1:
        cout << "b-";
        break;

    case 2:
        cout << "c-";
        break;

    case 3:
        cout << "d-";
        break;

    case 4:
        cout << "King-";     //特色情况King，只有King1和King2两种情况
        break;

    default:
        break;
    }
    if (i < 4)
    {
        if (j > 0 && j < 10)
            cout << j + 1;
        else if (j == 10)     //将10~12转化为J、Q、K，0转化为A
        {
            cout << "J";
        }
        else if (j == 11)
        {
            cout << "Q";
        }
        else if (j == 12)
        {
            cout << "K";
        }
        else if(j==0)
        {
            cout << "A";
        }
    }
    else
    {
        cout << j + 1;
    }
    cout << "   ";
}


int getline()

    int line;
    cout << "-----------------------------------------------------------------------------" << endl;
    cout << "Remember a card,and tell me what line it reside in(1/2/3):";
    cin >> line;
    while (!(line == 1 || line == 2 || line == 3))
    {

            }

我运行了一下，是对齐的呀
