/*
* The copy constructor in C++ is used to construct one object based on another.
* Specifically, a 'deep' copy is made, such that any heap-allocated memory
* is copied fresh. Thus, the copied-to object doesn't rely on the copied-from
* object after the constructor is called.
*
* The copy constructor is called as follows:
*
* Array a;
* // ... put data in a ...
* Array b(a);
*
* See below for implementation details.
*/
/*
* Function: Example copy constructor for an Array class.
* Parameters: An Array to make a deep copy of
* Effects: This is now a deep copy of other
* Notes: It's often convenient to use a 'copy' function, as this is also done in the =operator overload.
*/

copy(other); // make a deep copy of all memory in 'other' to 'this'
}
/*
* Function: copy
* Parameters: An array to make a deep copy of
* Returns: None
* Effects: Makes a deep copy of other into this.
