this program extends the earlier "online shopping cart" program. (consider first saving your earlier program).

(1) extend the itemtopurchase class per the following specifications:

private fields

string itemdescription - initialized in default constructor to "none"

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

public member methods

setdescription() mutator & getdescription() accessor (2 pts)

printitemcost() - outputs the item name followed by the quantity, price, and subtotal

ex. of printitemcost() output:

bottled water 10 @ $1 = $10

ex. of printitemdescription() output:

bottled water: deer park, 12 oz.
