🅿️ Parking Management System

An upgraded C++ console application for managing real-world parking operations — role-based access, dynamic rush-hour pricing, regex validation, and persistent file storage.

📌 About This Project

This is an upgraded fork of Rishav123918/Parking_Application_C-.

The original provided a basic parking structure. I rebuilt and extended it with:

• 🔐 Role-based login with security lockout
• 🧠 Rush-hour dynamic pricing engine
• 🔢 Regex-based number plate validation
• 📁 Persistent file storage with auto-load on startup
• 🧱 Full OOP redesign with 5 dedicated classes
• 🛡️ Complete input validation (dates, times, numerics)

🚀 Features

• 🔐 Role-Based Access — Admin and Staff login with password masking and lockout
• 🚗 Vehicle Management — Add Cars/Bikes, auto-generated tokens, duplicate detection
• 💰 Smart Fare Calculation — Time-based, hourly rounding, rush-hour pricing
• 💾 Data Persistence — Auto-saved to parking_data.txt, loaded on every startup
• 📊 Reporting & Search — Token search, revenue summary, car/bike breakdown
• ✅ Input Validation — Dates (leap year), times, numerics, number plate format

🧠 How It Works

User logs in (Admin / Staff)
        ↓
Add vehicle entry → token auto-generated
        ↓
System tracks duration from entry time
        ↓
Rush-hour check → applies dynamic pricing
        ↓
Checkout → fare calculated + data saved to file
        ↓
Reports & revenue summary available anytime

📌 Pricing Model

Vehicle	Normal (per hour)	Rush Hour (per hour)
Bike	Rs 10	Rs 15
Car	Rs 20	Rs 30

Rush Hours: 09:00 – 11:00 and 17:00 – 20:00

🛠️ Tech Stack

Layer	Technology
Language	C++17
Data Structures	STL (vector, algorithm, sstream)
Validation	Regex (<regex>)
Storage	File Handling (fstream)
UI	Windows Console API

---

🧱 OOP Architecture

5 dedicated classes:

Vehicle · Time · Date · SecuritySystem · ParkingSystem

Windows Console enhancements:

• _getch() — masked password input
• Sleep() — smooth UI transitions
• system("cls") — clean screen control

🎯 What I Changed from the Original

Feature	Original	This Version
Login system	Basic	Role-based with lockout
Pricing	Fixed rate	Rush-hour dynamic pricing
Plate validation	None	Regex-based format check
Data storage	Basic	Auto-load + continuous save
OOP structure	Minimal	5 dedicated classes
Input validation	Partial	Full (dates, times, numerics)
