• Smart Restaurant Management System (SRMS)

A console-based restaurant management application developed in ANSI C as part of the CSE124: Data Structure Lab course at Daffodil International University (DIU). This system operationalizes core data-structure concepts—including singly linked lists, queues, nested nodes, dynamic memory management, and file persistence—to simulate real-world restaurant workflow automation.

The project includes two operational modes:

• Manager Mode: Full administrative access with menu CRUD operations, stock management, order queue handling, and order serving.

• Customer Mode: Guided interface for browsing the menu and placing table-wise orders.

Features:

• • Role-Based Access: Manager & Customer workflows.

  • Persistent Storage: Auto-saving and loading of menu data.

  • Stock Management: Decreases stock automatically on order.

  • Queue-Based Order Handling: Ensures fairness and operational discipline.

  • Robust Validation: Prevents inconsistent or duplicate data entry.

  • Modular, Maintainable Structure: Clean, scalable ANSI C design.
