This program extends the earlier "Online shopping cart $($Part $1)"$ program. $($Consider first saving your earlier program$).$

Step $1$: Extend the ItemToPurchase class per the following specifications:

Parameterized constructor to assign item name, item description, item price, and item quantity $($default values of $0).(1$ pt$)$

Public member functions

SetDescription $()$ mutator & GetDescription$()$ accessor $(2$ pts$)$

PrintItemcost $()-$ Outputs the item name followed by the quantity, price, and subtotal

PrintItemDescription $()-$ Outputs the item name and description

Private data members

string itemDescription $-$ Initialized in default constructor to "none"

Ex$.$ of PrintItemCost $()$ output:

Bottled water $10$ @ $$1=$$$10$

Ex$.$ of printItemDescription$()$ output:

Bottled Water: Deer Park, $12$ oz$.$

Step $2$: Build three new files:

Shoppingcart. $h-$ Class declaration

ShoppingCart. cpp$-$Class definition

main. cpp$-$main $()$ function $($Note: mainO's functionality differs from the previous program.$)$

Build the ShoppingCart class with the following specifications.

Default constructor

Parameterized constructor which takes the customer name and date as parameters $(1$ pt$)$
