Redo Exercise 4 so that the customer can select multiple items of a particular type. A sample output in this case is:

Welcome to Johnny's Resturant ----Today's Menu---- 1: Plain Egg $1.45 2: Bacon and Egg $2.45 3: Muffin $0.99 4: French Toast $1.99 5: Fruit Basket $2.49 6: Cereal $0.69 7: Coffee $0.50 8: Tea $0.75

You can make up to 8 different selections Do you want to make selection Y/y (Yes), N/n (No): Y

Enter item number: 1

How many orders: 3

Select another item Y/y (Yes), N/n (No): Y

Enter item number: 8

How many orders: 1

Select another item Y/y (Yes), N/n (No): N

Welcome to Johnny's Resturant 3 Plain Egg $4.35 1 Tea $0.75 Tax $0.26 Amount Due $5.35
