Multi-threaded chat room service... The system contains one chat server (multi-threaded) and multiple chat clients.

Using c or c++

The server recognizes four commands,

CONN, MESG, MERR and GONE. CONN establishes a new client, sends a list of current clients, and notifies other clients a new person has joined the group. MESG sends a private message to the person designated. MERR sends last message again without an error if there is an error detected from receiver side. GONE removes an active client account and notifies all other members the client has left and kill the thread.
