Realtime Chat

A real-time chat application written in C from scratch using socket and network programming.

Overview

Realtime Chat is a simple yet powerful client-server chat application built from scratch in C using socket programming. The server listens for incoming client connections, while multiple clients can connect and exchange messages in real time. This project demonstrates low-level network programming, handling TCP connections, and implementing bi-directional communication between a server and multiple clients.

It was designed to be minimalistic, efficient, and provide a foundational understanding of networked applications in C. The application runs entirely on command-line interfaces, simulating real-time message exchange.

On the left is the server listening on port `8000`, and on the right is the client connected to port `8000`
