Also the cart has to capture these components of the items.
Start
-0- Welcome to the restaurant message
-1- Customer initial input
Ask customer to enter their name
-2- Ask customer if they would like to choose a seat from the unassigned seats.
-3- Create two dimensional arrays (string) to display the seat layout
If seats are not assigned, assign the seat to customer else display "XX" to indicate that the assigned seat is no longer available.
-4- If seats are available, assign to customers else display "Sorry there is no available seat at this time".
-5- Display a list of available food
-6- interface where a customer can choose one of the following options:
select an item
remove an item from a basket

-7- Create a temp basket
-8- make a payment for selected basket items
enter amount for payment
clear basket.
-9- Confirmation displaying:
customer's name.
seat number
list of ordered items
total cost of the order.
-1- Login system
Ask user enter username and password
Take the username and password
Check if it is correct login
else show a message that invalid username or password.
-2- List of products: -method
Name Code Price
-3- Select a product
Ask the user to enter item code
Entering item code
Take the item code
Ask for the quantity
Check if it is available in the stock
if available add it to the cart
else show a message out of stock
-4- Show cart with the total
-- Expand this as a method

In case the user press 0
The final basket will be displayed.
-break to terminate the while loop
-Otherwise continue the if loop.
