// Lab 9 - Lownum/Highnum
// By Perry Huang
/*
Write a program which asks the user to enter two numbers into
the variables lownum and highnum. The value lownum should be less
than the value highnum. If this is not the case, the program should
exchange the numbers, placing the low value into lownum and the
high value into highnum. Have a function in the program which looks
at each number individually and reports back which of the following
ranges the number lies in: below 0, from 0 to 50, 51 to 100, 101 to 150,
or
above 150. Each number should be output along with which variable it
is being stored in and what range it lies in.
BEWARE: This program uses several of the structures we have been
talking about lately. Be sure not to undertreat this problem.
