Chat Application

This project is a simple multithreaded chat application written in C++. It includes a server and a client implementation, allowing multiple clients to connect and exchange messages anonymously.

Features

  • Anonymous Communication: Each client is assigned a random unique name upon connection.
  • Multithreading: The server handles multiple client connections concurrently.
  • Message Broadcasting: Messages sent by one client are broadcast to all other connected clients.

Requirements

  • A Linux-based operating system or WSL (Windows Subsystem for Linux).
  • A C++ compiler supporting C++11 or later (e.g., g++).

Compilation

Server

  1. Navigate to the server/ directory: 
    cd server
  2. Compile the server code using the Makefile: 
    make

Client

  1. Navigate to the client/ directory: 
    cd client
  2. Compile the client code using the Makefile: 
    make

Usage

Running the Server

  1. Start the server by running the compiled executable: 
    ./chat_server
  2. The server will start listening for incoming connections on port 8080 by default.

Running the Client

  1. Start the client by running the compiled executable: 
    ./chat_client
  2. Enter the IP address of the server when prompted.
  3. Begin chatting! Messages will be sent with a randomly assigned anonymous name.
  4. Type exit to disconnect from the server.

Example Interaction

Server:

Server started on port 8080. Waiting for clients...
New client connected.
New client connected.
Received message from client: [AnonUser1]: Hello, everyone!
Received message from client: [AnonUser2]: Hi!

Client 1:

Enter server IP address: 127.0.0.1
Connected to server as AnonUser1. You can start typing messages.
[AnonUser1]: Hello, everyone!

Client 2:

Enter server IP address: 127.0.0.1
Connected to server as AnonUser2. You can start typing messages.
[AnonUser2]: Hi!

Notes

  • Ensure the server is running before starting the client.
  • The default communication port is 8080. Modify it in the code if needed.
