Overview

The Text-Based Facebook Replica is a console-based social networking application developed in C. It simulates core social media functionality such as user registration, login, post creation, friend management, and viewing posts, all through a text-based interface.

The project was built to strengthen fundamental programming concepts in C, with a strong focus on linked lists, dynamic memory management, modular design, and user interaction through the terminal.
