About Project :

This project is a basic prototype of a Restaurant Menu and Billing System developed in C programming. It demonstrates the core functionality of a restaurant billing process in a console-based environment.

Key Features:

Menu Management: Allows adding new items with their name and price, and viewing the current menu.

Order Processing: Takes customer orders by selecting menu items and specifying quantities.

Bill Generation: Calculates the total bill for the customer and displays a formatted summary.

Prototype Purpose: This implementation is a simple, beginner-friendly model designed to demonstrate fundamental C programming concepts like structures, arrays, functions, and user input handling.

This project serves as a foundation for more advanced systems in the future, such as integrating file-based storage, tax calculations, discounts, or a graphical interface.

Learning Outcomes

• By using the Restaurant Billing System, you can:

• Easily manage a restaurant menu by adding, viewing, or updating menu items.

• Take customer orders and generate bills quickly and accurately.

• Understand how a basic billing system works, making it easy to customize or expand for your own needs.

• Learn to experiment with C programming by modifying menu items, prices, or order logic.

• Optionally, extend the system with features like order history, taxes, discounts, or file-based storage for persistent data.

Step 1: Open Terminal in VS Code

Open your project folder: Restraunt Billing System (where your files are: main.c, menu.c, menu.h)

Open terminal: Ctrl + `` (backtick) or View → Terminal

Step 2:Compile the Program

gcc main.c menu.c -o restaurant.exe

This compiles your C files and creates restaurant.exe.

If no errors appear, compilation is successful.

Run the Program

.\restaurant.exe

You should now see:
