assignment 1.1A perhaps?
Write a validate function, to take an input from the
user or the command line, and return a number within
a specified range, or print an error message and
allow the user the ability to retype the improper input,
without having to have the user retype *all* of the
other inputs (such as only one parameter on the command
line being improper... just fix that one parameter)
