无法弄清楚崩溃

首先让我说这是一个学校练习。我正在努力学习，而不仅仅是复制/粘贴答案。正确方向的提示会很棒。如果这个问题不符合本网站的任何规则，我很抱歉。

所以我的问题是我创建了一组卡片，并在数组中列出了每张卡片（一个 int）。第一个工作正常，但在第二个卡片组上我的程序崩溃了。

我留下了一些代码。我并不担心所有的功能。我的程序在构造器区域崩溃。它编译良好，但在执行时崩溃。那里肯定有一个非常简单的错误。谢谢！

卡片集.cpp

#include <iostream>
#include "CardSet.h"
using namespace std;

CardSet::CardSet()
{
    nCards = 0;
}

CardSet::CardSet(int Input_Card_Amount)
{
    nCards = Input_Card_Amount;
    int quot = (int)nCards / 52;
    int rem = nCards % 52;
    int Sets_Of_Cards = 0;
    int Card_Index = 0;
    while(Sets_Of_Cards != quot)
    {
        for(int Card_Counter = 0; Card_Counter < 52; Card_Counter++)
        {
            Card[Card_Index] = Card_Counter;
            Card_Index++;
        }
        Sets_Of_Cards++;
    }
    for(int Card_Counter = 0; Card_Counter < rem; Card_Counter++)
    {
        Card[Card_Index] = Card_Counter;
        Card_Index++;
    }
}

CardSet::~CardSet()
{
    delete[] Card;
}

主程序

int main()
{
    CardSet CardSet1(12), CardSet2(12), CardSet3, CardSet4, CardSet5, CardSet6;

    cout << "BEGINNING OF CARDSET TESTS . . .  "<< endl << endl;

    cout << "Test 1: Constructors:" << endl;
    cout << "CardSet1 Size: " << CardSet1.Size() << endl;
    cout << "CardSet3 Size: " << CardSet3.Size() << endl;
    cout << "Printout of CardSet1:" << endl;
    CardSet1.Print();
    cout << "Printout of CardSet2:" << endl;
    CardSet2.Print();
    cout << endl;
    enter code here
    cout << ". . . END OF TESTS"<< endl;
    return 0;
}
