The Cafeteria Management System is a console-based application written in C that helps manage food items, orders, and customer interactions within a cafeteria. It incorporates data structures such as linked lists, stacks, and queues to efficiently handle various operations.

Cafeteria Management System

This is a simple Cafeteria Management System implemented in C. The system allows users to manage a menu of food items, place orders, and perform administrative tasks such as adding, editing, and deleting food items. The system also includes features to display order summaries, manage a stack of orders for each table, and process orders from a queue.

Features

1. Display Menu: View the current menu of food items with details such as name, price, and quantity.

2. Place Order: Customers can place orders by specifying their name, the item they want to order, and the quantity.

3. Display Order Queue: View the current orders in the queue, including customer names, item names, quantities, and prices.

4. Admin Login: Authenticate as an admin to access additional features.

5. Admin Features:

   • Add Food Item: Add a new food item to the menu.
   • Edit Food Item: Modify the details of an existing food item.
   • Delete Food Item: Remove a food item from the menu.
   • Place Order: Admins can also place orders on behalf of customers.
   • Display Order Summary: View a summary of all placed orders, including total sales.
   • Display Stack: View the current stack of orders for each table.
   • Display Order Queue: View the current orders in the queue.
   • Process One Order: Process and dequeue one order from the queue.

6. Save Menu to File: The system saves the current menu to a file named "menu.txt" to persist data between sessions.

7. File Operations:

   • Load Menu from File: Load the menu from the "menu.txt" file at the start of the program.
   • Save Menu to File: Save the current menu to the "menu.txt" file.

Usage

1. Clone the repository:

   git clone https://github.com/your-username/cafeteria-management-system.git

2. Compile the program:

   gcc cafeteria_management_system.c -o cafeteria_management_system

3. Run the executable:

   ./cafeteria_management_system

4. Follow the on-screen instructions to interact with the Cafeteria Management System.

Note

• The system uses a simple text file ("menu.txt") to store the menu items. Make sure the file is present in the same directory as the executable.

  • Username: admin
  • Password: 123

• The system includes a basic authentication mechanism. Users need to enter the correct username and password to access admin features.
