CS 357 ASSIGNMENT #2 - DATAGRAM IMPLEMENTATION -

HOW IT WORKS : 

A datagram is sent to reciever, the reciever's name is taken from the command
line args.  
The command line is datagram.cc followed by the "host name" & the "port
number"

The user is then prompted for the appropriate data. (in our case a stock
ticker symbol).
The data is reads in & stored.

Next the datagram socket is opened. After successful opening of the datagram
socket, the host name is looked up . If the datagram socket could not be
opened successfuly then an error message is sent out.

If the host name is found, the host address is copied and an address structure
is set up.

At this point the data (stock symbol) is sent, if there is no output returned
an error message is displayed.

After all the Data to be sent has been sent , the socket is closed.
