A real-time, console-based TCP chat application implemented in C++.
The project uses a client–server architecture and demonstrates low-level socket programming, multithreaded I/O, and thread-safe console handling.

• Client

  • ChatClient_cross_platform.cpp — Cross-platform client (Windows & Linux)
  • ChatClient_win_only.cpp — Windows-only client using Winsock

• Server

  • ChatServer_cross_platform.cpp — Cross-platform server (Windows & Linux)
  • ChatServer_win_only.cpp — Windows-only server using Winsock

• Uses TCP sockets (AF_INET, SOCK_STREAM) for reliable communication
• Multithreaded design with separate send/receive threads
• Thread-safe console output using std::mutex
• Graceful connection handling and clean shutdown (quit / exit)
• Full-line input handling with username-prefixed messages
