help me to write c code of this problem

A simple TCP based chat server could allow users to use any TCP client (telnet, for example) to communicate with each other. For this question you should consider a single process, single thread server that can support exactly 2 clients at once, the server simply forwards whatever is sent from one client to the other (in both directions). Your server must not insist on any specific ordering of messages – as soon as something is sent from one client it is immediately forwarded to the other client. As soon as either client terminates the connection the server can exit

BEFORE REPORTING ME: if you actually look at it, it's for an old 2003 midterm that the faculty intentionally put up for students to study from. I see nothing wrong with linking to it. However, the OP should transfer to a school where the faculty doesn't engage in plagiarism.

Goes to show that the instructor is a lazy cheater as well... lame.
