Features

• Admin authentication system

• Add, remove, and manage products

• Edit product price and quantity

• Category-based inventory:

  • Food & Beverages
  • Self Care
  • Household Items

• Persistent storage using file handling

• Basic encryption/decryption for stored data

• Automatic data compaction after deletion

---

Concepts Demonstrated

• Object-Oriented Programming (OOP)
• Inheritance and polymorphism
• File handling (ifstream, ofstream)
• Arrays and data organization
• String manipulation
• Basic encryption logic (character shifting)

---

⚙️ How It Works

• Products are stored in 2D arrays categorized by type
• Admin can manage inventory through a menu-driven interface
• Data is saved in a file (hello.txt)
• Before saving, data is encrypted using a custom character-shift method
• On loading, data is decrypted back into usable form

---

📌 Notes

• The encryption system is designed for learning purposes only and is not secure for real-world applications
• The system uses fixed-size arrays ( And... You can change it yourself )
• Works in a console environment
