This repository contains a command-line messenger application written in C, developed as part of the Introduction to Computing Systems and Programming (ICSP) course at the University of Tehran. The application allows users to register, log in, create posts, like posts, and search for other users in a simple and interactive command-line interface. This project demonstrates fundamental programming concepts and data handling techniques, making it an educational assignment to enhance programming skills.
