/* Instructions:
Complete each of the following six incomplete short functions.
For all but the last one, you are given a stub consisting of a header (prototype)
and a body containing only a return statement.
The header should not be changed.
You may find it necessary to change the return statement.

For the last incomplete function, orderCheck, you are not given any code
at all.  This will result in a warning and a linker error until you write some
appropriate code for it.  (If this bothers you, do it first.)

The code for main is a test harness.  It should not be changed.  Once you have 
completed the functions, run the program and compare your output with the
program's "should be" output.  Your version should give the exact same results.
Of course, your functions should operate correctly on all inputs,
not just the ones that happen to be tested in main!

/*Define a function orderCheck which takes three values 
	and determines whether the three are in non-decreasing order, 
        printing one or the other of the following messages, as appropriate, 
        on a line preceded and followed by a newline:
	The three numbers ARE in order
	The three numbers are NOT in order
	
	The function does not return any value.  For more hints, look at the
	calls in main, and see what the answers should be (given in the 
        comments).
