Chit chat server

To build this project, follow the steps below:

cd build
cmake ../
make

This will generate two executables, server and client, which you can run by ./server and ./client respectively.

💬 Server (server.cpp)

• Create and bind a TCP socket (socket(), bind(), listen())

• Use select() to handle multiple client sockets

• Accept new client connections and store their file descriptors

• Read data from connected clients

• Broadcast each received message to all other clients

• Handle client disconnects (remove closed sockets)

👤 Client (client.cpp)

• Connect to server using socket() + connect()

• Launch a std::thread to receive messages from server continuously

• Use the main thread to read user input and send to server

• Gracefully handle disconnects (e.g., Ctrl+C)
