Some demo programs showing how to use I/O functions in C.

(1) dispfile.c

A quick program that uses POSIX functions (unistd.h) to display the
contents of a given text file.

(2) chatter.c

A small chatterbot program, that repeats everything you type to it.

==== Instructions ====

To compile the code, run the "make" command:

    $ make

This will generate two executables: dispfile, and chatter.

==== Usage ====

(1) dispfile

Run the dispfile executable by passing it a filename, ie:

    $ ./dispfile myfile.txt

(2) chatterbot

First, run the chattrebot by doing:

    $ ./chatterbot

Then, talk to it by typing into the terminal, and pressing <ENTER>.

To quit, type 'q', and hit <ENTER>.
