Adding and Subtracting integer arrays

[Reclaimer78]

Ok so I am currently working on a program that uses a class to store integer arrays. I have most of the code done, but I am having trouble on the main.cpp part of my program. The program should display this:

OBJ 1:
2 3 4
OBJ 2:
1 4 -2
Addition:
OBJ 1 =
3 7 6
Subtraction:
OBJ 1 = 1 -1 6



But when I run and compile my program, this is what I get:


OBJ 1:
2 3 4
OBJ 2:

ADDING:
OBJ 1 =
4 6 8
Subtraction:
OBJ 1 =


I would greatly appreciate it if someone could help me with this. Here is my current main.cpp:

#include <iostream>

#include "SafeArray.h"

using namespace std;



int main()

{
   // Declare a SafeArray object
    Safe obj;
    Safe obj2;
    int x;

    obj.set(2,0);
    obj.set(3,1);
    obj.set(4,2);
    
    
    cout << "OBJ 1: " << endl;
    obj.print();

    cout << "OBJ 2: " << endl;
    obj2.print();

    cout << "ADDING: " << endl;
    obj.add(obj2);

    cout << "OBJ 1 = " << endl;
    obj.print();

    cout << " Subtraction: " << endl;
    obj.subtract(obj2);

    cout << " OBJ 1 = " << endl;
    obj.print();
    


   return 0;

}
