Printer Deletes Its Own Cartridge

Write TWO classes. Printer owns a Cartridge that it creates on the heap in its constructor.

Cartridge (write it first):
``
Cartridge(int ink);       // private member: int inkLevel
int getInk() const;
void use(int amount);     // subtract amount from inkLevel
`

Printer private members: Cartridge* cartridge; and int pagesPrinted;. Public interface:
`
Printer(int startingInk);   // cartridge = new Cartridge(startingInk); pagesPrinted = 0
~Printer();                 // the cartridge is owned here - release it
void printPages(int pages);
int inkLeft() const;        // the ink still in the cartridge
int pages() const;          // pages actually printed, over all calls
`

printPages(int pages) prints up to that many pages at 2 ink each. If the cartridge has less than 2 ink left, printing STOPS and the remaining pages are skipped. Every page printed adds 1 to pagesPrinted.

The driver reads startingInk firstRequest secondRequest. For the input:
`
10 3 4
``

the exact output is what is shown in Expected Output.

Do NOT write a main function.
