Write a C++ program for billing system of a restaurant. The program should perform the following tasks:
Show menu of items/dishes to customers
It should allow customers to select multiple items (by showing menu again and again continuously until he/she selects the “Quit” option)
Finally, when the customer quits, it should prepare the
bill (containing the details of all the orders and the total) and save it in a
file named “bills.txt”.
Assume that the following items are offered in the restaurant
Dish/Item Name Price
Omelet $1.45
French Omelet $2.45
Muffin $0.99
French Toast $1.99
Fruit Basket $2.49
Cereal $0.69
Coffee $0.75
Tea $0.50
Note: The billing amount should also include a 5% tax.
