SmartCart

Overview

This project implements a server-client architecture for an Inventory Management System using socket programming in C. The system involves an Admin (server) and User (client) with communication facilitated through sockets. It provides fundamental functionalities for product management, cart handling, and payment processing. Concurrency control mechanisms, including locks, are implemented to ensure data integrity during critical operations.

Problem Statement

Admin Menu

1. Add/Del a product: Add or delete a product from the inventory.
2. Update quantity/price: Modify the quantity or price of an existing product. Generates a log file with stock levels and product details upon exit.

User Menu

• Display Products: Lists all available products: P_ID, P_Name, Cost.
• Manage Cart: View, add products with quantities, and edit the cart.
• Payment: Initiate a payment process by entering the amount in the terminal. Generates a receipt log file upon completion.

Additional Features

• Concurrency Control: Implements locks during critical operations, preventing conflicts during payment gateway access or admin product interaction.
• Product Locks: Ensures exclusive access to products in the cart and products updated by the admin.
