Aim: 
To build a simple network involving three nodes with following instructions.
1. One of the nodes will be a client and the other two nodes will be servers.

2. The client can request for a file from the servers and any server having the file will send the
file, also flag an error message if the server does not have the file. If both servers have the
file, send the file from any of the servers.


Compilation instruction
1) client server is hard coded in file itself
2) only port are provided as command line for each file
3) 2 port are provided corresponding to each server for client.c file.
