Instructions

First task: write a program that, given a port and an ip address or hostname, accepts input from the command line and sends it to that port and address.

Also, write a program that, given a port, listens on that port and prints anything it receives.

You can use a program called netcat (or 'nc' more often than not) to test this, since it does basically those things.
