Array Class

Wait for it (9)
Hello, I am doing an Array of object type, but I need some help because I want to create a constructor that can be something like:

Array(int A[], int size);

but I dont know how to do it, because the problem is that it is creating 100 elments instead of 10 because of the first constructor. I just help me with thgis part not with the other that are incomplete. Thanks you.

Here is the code

What is line 14 all about ?
It looks like a default constructor but you're trying to store a value into an int data type itself.

Sorry I got the answer, I was not calling the function correctly, because instead doing like this:

Array (arr, 10);

should be like this:

Array (New Object)(arr, 10);

Array B(arr, 10);

That copies and create a new Object of an Array with 10 elements.

Thanks you Soranz anyway.

Here is the complete code if someone wants to see it:
