How to write a simple restaurant reservation system using C?

The catering industry is a fast-paced industry, and restaurants often need to face busy reservations. In order to effectively manage reservations and improve service quality, many restaurants use electronic reservation systems. This article will introduce how to use C to write a simple restaurant reservation system.

First, we need to define the basic functions and data structure of the restaurant reservation system. The restaurant reservation system mainly has the following functions:

1. View available seats in the restaurant
2. Reserve seats
3. Cancel seat reservation
4. View already Reserved seats
5. Exit the system

Next, we need to define some data structures to store the restaurant’s seating information. Considering that the restaurant may have different areas and number of seats, we can use a two-dimensional array to represent the status of the seats. 1 means the seat has been reserved, 0 means the seat is free. We can also use another array to record the names of customers who reserved seats.

When the program starts running, we first need to initialize the seat status array and reservation record array. Then enter a loop to perform the corresponding function according to the user's selection.

Users can select functions by entering different numbers. When the user chooses to view the available seats in the restaurant, the program will traverse the seat status array and display the location of the available seats to the user. Users can choose to reserve seats based on the displayed information. When the user chooses to reserve a seat, the program will prompt the user to enter the name and seat number, set the corresponding position in the seat status array to reserved, and record the customer's name in the reservation record array. When the user chooses to cancel the reservation, the program will prompt the user to enter the seat number to cancel the reservation, set the corresponding position in the seat status array to idle, and delete the corresponding record from the reservation record array. When the user chooses to view the reserved seats, the program will traverse the reservation record array and display the reservation information to the user. When the user chooses to exit the system, the program ends the loop and exits.

In order to increase user-friendliness, we can add error handling logic to the program. For example, when the seat number entered by the user is illegal, the program will prompt the user to re-enter it. When the seat number entered by the user has been reserved, the program will prompt the user to reselect.

The above is a simple example of a restaurant reservation system written in C. Of course, this is just a basic version and you can make appropriate modifications and extensions according to actual needs. Through learning and practice, you can further improve your programming skills and design a more complex and practical restaurant reservation system.
