# 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:



   ```bash

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

   ```



2. Compile the program:



   ```bash

   gcc cafeteria_management_system.c -o cafeteria_management_system

   ```



3. Run the executable:



   ```bash

   ./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.



- Admin credentials are hardcoded as follows:

  - Username: admin

  - Password: 123



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