Hello Sir,
My name is Yang, I am a professional Linux C programmer, I have read your TCP/IP chat program details, also, I have done similar work before, so I have confidence to complete it in 3 days.
To write a TCP/IP based chat program is simple, there need a server and client program, if you only need 2 user send message to each other, this is simple, or if you want to multiple user can login to server, and communicate to everyone, it's more complex.
if you have extra requirements, please tell me.
thanks!
