🚀 Key Features

• Patient Registration: Store patient details including Name, Age, Disease, and Assigned Ward.
• Doctor Database: Maintain a record of available doctors and their specializations.
• Appointment Scheduling: Link patients to specific doctors.

🛠️ Technical Overview

This system is architected using:

1. Structures: To handle complex data types (e.g., a Patient struct containing a Date struct for admission).
2. File I/O: Using rb+, ab+, and wb modes to ensure data is updated without overwriting the entire database.
3. Search & Sort: Simple algorithms to organize records by ID or Name.
