Re: some concerns

That's concerns...

What have you tried to do? The rules of the forum say that you need to make an attempt at a solution before anyone can help you. See Homework Help here: https://www.physicsforums.com/showthread.php?t=5374.

What's "the cmath?" How would it help to know whether the numbers are even or odd? That's not anything that's relevant in this problem.

cmath is the header math.h. You don't need any of the functions whose prototypes are in math.h if all you want to do is determine whether a number is even or odd. The modulo or remainder operator (%) is all you need. You don't need to include any headers to use it.

This operator takes two operands, and returns the remainder when the first operand is divided by the second.
For example 5 % 2 == 1, and 8 % 2 == 0.

#!perl
print "Enter three numbers: ";
print "Numbers in ascending order: ".join(" ",sort {$a <=>$b} (split /\D+/,<>))."\n";

That's not going to be much help to the OP since he will be writing C++ code.
