A tiny minimalistic CHAT Client Program writen in C

A friend of mine (Dido) who is learning C programming, has written a tiny chat server / client (peer to peer) program in C. His program is a very good learning curve for anyone desiring to learn basic C socket programming.
The program is writen in a way so it can be easily modified to work over UDP protocol with code:

struct sockaddr_in a;
a_sin_family=AF_INET;
a_sin_socktype=SOCK_DGRAM;

Here are links to the code of the Chat server/client progs:

Tiny C Chat Server Client source code

Tiny C Chat Client source code

To Use the client/server compile on the server host tiny-chat-serer-client.c with:

$ cc -o tiny-chat-server tiny-chat-server.c

Then on the client host compile the client;

$ cc -o tiny-chat-client tiny-chat-client.c

On the server host tiny-chat-server should be ran with port as argument, e.g. ;

$ ./tiny-chat-server 8888

To chat with the person running tiny-chat-server the compiled server should be invoked with:

$ ./tiny-chat-client 123.123.123.123 8888

123.123.123.123 is the IP address of the host, where tiny-chat-server is executed.
The chat/server C programs are actually a primitive very raw version of talk.

The programs are in a very basic stage, there are no condition checks for incorrectly passed arguments and with wrongly passed arguments it segfaults. Still for C beginners its useful …
