Lab $4$

Question: Create an Array class according to the UML.

UML:

$-$data: int$*$

$-$size: int

$+$Constructor: constructor with parameters

$+$Copy constructor:

$+$Destructor:

Then, create a new class: ArrayNew. Use unique pointer to replay the raw pointer you used before.

TA explanation:

You need to create $4$ files. $2$ files for $.$h and $2$ for $.$cpp $(.$h and $.$cpp for Array and $.$h and $.$cpp for ArrayNew$).$You need to use a normal pointer in the Array class and a unique pointer for ArrayNew class. Don$$t connect the array class and ArrayNew class. Both are separate and have different pointers. $($Array class has normal raw pointer and ArrayNew class has unique pointer $).$You need to define a parametrized constructor, copy constructor and a destructor.

Despite all the instructions, I still have no idea what to do and what they are asking for. The TA said to use a for loop to iterate through the array. That, however is about all I understand. Please help me understand this and walk me through what to do$.$ Including code is extremely helpful $($as long as I understand it$).$
