Address Book

The Address Book is a simple console-based application designed to manage contact information. It allows users to store, search, edit, and delete contact records. This project simulates a real-world scenario of developing a personal information management tool. The system will operate in a text-based interface and use a local data file for persistent storage.

Features

• Add a new contact
• View all contacts
• Edit existing contact information
• Delete a contact
• Search for a contact by name or phone number
• Save and load contact data from a file

User Interface

Text-based menu with interactive options (no TUI/GUI).

• Add / Edit / Remove contact
• Search (by name or phone)
• List all contacts
• Exit with auto-save

Design

• OOP design ensures readability and flexibility.
• Encapsulation and Abstraction hides common and separates specialized behavior.
• Polymorphism unified handling of all types via virtual methods.
• Separation of Concerns between UI, Core, I/O, and Search.
• Open/Closed Principle new contact types can be added easily.
• Interface Segregation and Dependency Inversion UI layer decoupled from core logic.
• Strategy Pattern modular search algorithms without changing the core logic.
• Factory Pattern dynamic creation of objects from file data.
• RAII and Smart Pointers unique_ptr ensures safe memory management.
• STL Containers vector used for flexible and efficient contact storage.
• Persistence layer abstracts file reading/writing logic.
• Consistent Data uniform text representation makes saving/loading clearn and extendable.
• Defensive Programming and Input Validation
• Testable Architecture components can be tested independently
