Low Latency C++ Socket Communication

This project provides a low-latency C++ socket-based communication system featuring a multithreaded server and a responsive client application for real-time messaging.

Features

• Multithreaded server supporting multiple clients.
• Real-time message broadcasting with low latency.
• Optimized networking using non-blocking I/O and select-based monitoring.
• Efficient connection management with error handling.

Requirements

• Windows OS
• Microsoft Visual Studio or a compatible C++ compiler
• Winsock2 library (included in Windows SDK)

How to Run

Step 1: Compile the Server

1. Open the server code in your C++ IDE.
2. Compile the server code to generate the executable.
3. Run the server executable. It will start listening on port 9909.

Step 2: Compile the Client

1. Open the client code in your C++ IDE.
2. Compile the client code to generate the executable.
3. Run the client executable and connect to the server using IP 127.0.0.1 and port 9909.

Step 3: Test Communication

1. Start the server first and then run one or more clients.
2. Type a message in the client console to send it to the server.
3. Messages will be broadcast to all connected clients.
