🏥 Hospital Management System

A console-based Hospital Management System built using C++ and core Object-Oriented Programming (OOP) concepts.

This project simulates a real hospital workflow with separate interfaces for Admins, Doctors, and Patients, allowing appointment booking and management with persistent file storage.

🧠 OOP Concepts Used

Concept	How It Was Used
🔒 Encapsulation	Private/protected members with getters & setters
🧬 Inheritance	Doctor, Patient, and Admin inherit from User
🎭 Polymorphism	Virtual functions like displayInfo()
🧱 Abstraction	Pure virtual methods in User
🏗️ Constructor Overloading	Multiple constructors in classes
💾 File Handling	Persistent storage using text files
⚠️ Exception Handling	try-catch and throw statements
🧹 Dynamic Memory	Arrays allocated using new[] and delete[]
