HW14: A simple text displaying program.

Write a program called "display" that is invoked with one command-line
argument:

	display argument

The argument is assumed to be a positive integer. We will call it
X for now.  (Remember that command line arguments are strings,
you must convert it to an integer.)

The program reads from standard input and writes each character
that it reads to standard output. However, on those lines that
have more than X characters, it replaces the first space
or tab character after the first X characters with a newline.
It continues to copy characters from the rest of the line to
standard output. Again, if there remain more than X characters,
it replaces the first space or tab character after X characters
with a newline...  and so on.

In other words, once X characters are written to a line of
standard output, the next tab or space in the line will be
replaced with a newline character.


EXAMPLE:

So, if X were 10 and the input was (note: the dashed lines
are NOT part of the input or output!):

-------
...
because I am involved in Mankinde;
and therefore never send to know 
FOR WHOM THE BELL TOLLS 
It tolls for thee
-------

Then the output would be:
-------
...
because I am
involved in
Mankinde;
and therefore
never send
to know 
FOR WHOM THE
BELL TOLLS 
It tolls for
thee
-------

The program should be in a file called "display.c".



Make sure the program compiles and executes properly before turning it in.
BE SURE TO TEST IT!

Make sure that the program is properly designed and formatted. Distinct logical
tasks should be carried out by distinct functions. Remember to write a comment
before each function explaining what its purpose is.

WHAT TO SUBMIT VIA TOTEACH:
