Food Menu Program

Problem: Create a Java Program that uses Control Statements (must use switch-case statement and ladderized if-else ) that presents a menu of a fast food chain at least 5.

Consider the following:
a. The user of your program is the costumer.
b. The Costumer selects one menu.
c. Consider Discounts
         c.1  If the costumer is a Senior Citizen (give 20% Discount from the total amount due)
         c.2 If the costumer is a Student (give 5.5% Discount)
         c.3 If None of the (2) options No Discount will be given
