Task

Create a program $($Filename: menu.cpp$)$ that will simulate ordering different goodies from the Trolley as if you are on your way to Hogwarts. You will ask the user how many of certain candy items they'd like, calculate, and print the total for the customer, including wizard tax. $($Yes$,$ there's even taxes in the wizarding world$).$

Declare $4$ CONSTANT double variables representing the prices of each item on the menu. The prices should be:

Bertie Botts Every Flavour Beans: $$4\mathrm{.}00$

Chocolate Frog: $$1\mathrm{.}50$

Exploding BonBons: $$2\mathrm{.}50$

Cauldron Cake: $$6\mathrm{.}25$

Use these variables anytime you need to do calculations that involve the prices of these items, or anytime you DISPLAY the prices of these items.

Declare a CONST double variable to represent the Wizard Tax rate of $6\mathrm{.}5\%$
