🚗 Vehicle Management System

Structured Command-Line Application in C

---

📌 Overview

The Vehicle Management System is a menu-driven command-line application developed in C.
It simulates a lightweight vehicle database system using structured programming and manual data management techniques.

The system allows users to add, view, search, update, and delete vehicle records while ensuring data consistency and integrity.

This project demonstrates practical implementation of structured data handling without using external databases or file storage.

---

🎯 Objectives

• Implement structured data management using struct
• Handle multiple records using arrays
• Enforce unique identifiers
• Maintain record consistency during updates and deletions
• Design a continuous menu-driven system
• Apply modular programming principles

---

🏗️ System Design

🔹 Data Structure

Each vehicle record contains:

• Vehicle ID (Unique Numeric Identifier)
• Vehicle Type (Car, Bike, Bus, Truck, etc.)
• Model Name
• Brand / Manufacturer
• Year of Manufacture
• Engine Capacity (cc or descriptive text)

Optional attributes may include:

• Color
• Seat Count
• Fuel Type

All records are stored in an internal array structure.

⚙️ Core Functionalities

1️⃣ Add New Vehicle

• Accepts all vehicle attributes
• Validates uniqueness of Vehicle ID
• Inserts record into storage
• Confirms successful addition

2️⃣ Display All Vehicles

• Lists all stored vehicles
• Displays complete details in formatted structure
• Handles empty system condition

3️⃣ Search Vehicle

Supports:

• Search by Vehicle ID
• Search by Vehicle Type
• Search by Model Name

Displays full details of matching records.

4️⃣ Update Vehicle

• Locate vehicle using ID
• Display existing information
• Modify selected fields
• Save updated record without affecting others

5️⃣ Delete Vehicle

• Remove record by ID
• Shift array elements to maintain continuity
• Confirm deletion success

6️⃣ Exit System

• Clean and safe termination

---

🔐 Functional Constraints Implemented

• Manual data storage (arrays and structures only)
• No external database or file handling
• Maximum record limit (configurable)
• Unique Vehicle ID enforcement
• Input validation for numeric and text fields
• Continuous menu loop until explicit exit
• Record integrity preservation after update/delete

---

🚀 Advanced Features (Extended Capabilities)

The system architecture supports extension for:

• Multi-condition filtering
• Sorting by year, brand, or engine capacity
• Duplicate detection across attributes
• Bulk delete operations
• Partial updates for matching records
• Summary statistics generation
• Grouping vehicles by category
• Dynamic capacity expansion
• Cloning vehicle templates
• Undo last operation feature
