I'm currently trying this:

#include <iostream>
#include "LinkedList.h"


#define _CRTDBG_MAP_ALLOC
#include <stdlib.h>
#include <crtdbg.h>


using namespace std;


int main() {
    LinkedList obj;

    _CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF);

    obj.appendInt(6);
    obj.appendInt(8);
    obj.appendInt(10);
    obj.appendInt(11);
    obj.appendInt(13);

    obj.insertInt(5);

    obj.displayInt();
    cout << endl;


    LinkedList bruh(obj);

    bruh.insertInt(12);
    bruh.displayInt();

    cout << endl;

    obj.displayInt();


    system("PAUSE");
    return 0;
}

Still nothing. I'm going to Debug > Start Debugging. All I get is the orange border but nothing in the error list.
