Based on the specifications provided, here's an algorithm outline for the Restaurant Management System:

Structures and Enumerations:

Structures:

Reservation: time, customer name, number of people

Table: size, table number, number of people seated, availability

Order: associated table, associated reservation, menu items, number of items ordered, completion status, payment status

Enumerations:

Menu items with corresponding prices

Arrays:

Array to manage reservations

Array to manage tables

Array to manage orders

Functions:

makeReservation$()$: Collects information and adds a reservation to the system.

checkInReservation$()$: Displays all unchecked reservations and assigns a table to the checked$-$in reservation.

enterOrder$()$: Enters an order for a table.

completeOrder$()$: Marks an order as completed.

calculateAndPayBill$()$: Calculates and pays the bill including tax and tip.

closeRestaurant$()$: Exits the program if there are no pending reservations and outstanding orders.

Main Menu UI:

Display main menu options

Prompt user for input

Call corresponding functions based on user input

Continue until the restaurant is closed

Initialization:

Initialize arrays for reservations, tables, and orders

Set up tables according to their sizes and numbers

Validation:

Validate inputs for reservations, orders, and payments to ensure data integrity

Check for available tables before assigning one to a reservation

Flowchart:

Create a flowchart using LucidChart or Draw.io demonstrating the main components and the flow of the program, including user interactions and system processes.

Implementation Notes:

Use simple arrays and structures as instructed, avoiding classes, pointers, vectors, or other advanced constructs.

Ensure clear documentation at the beginning of the program as per the provided example.

Test the program thoroughly to handle various scenarios and edge cases.

This algorithm outline should provide a structured approach to developing the Restaurant Management System according to the given specifications. Use LucidChart or Draw.io to create a flowchart that demonstrates the main components of the project
