Even Odd in Every Language

Welcome to the Even Odd page! Here, you'll find a description of the project as well as a list of sample programs written in various languages.

Description

An even number is an integer which is "evenly divisible" by two. This means that if the integer is divided by 2, it yields no remainder.

An odd number is an integer which is not evenly divisible by two. This means that if the integer is divided by 2, it yields a remainder of 1.

Requirements

Create a file called "Even Odd" using the naming convention appropriate for your language of choice.

Write a sample program which accepts an integer on the command line and outputs if the integer is Even or Odd.

Testing

The following table contains various test cases that you can use to verify the correctness of your solution:

Description	Input	Output
no input	None	Usage: please input a number
empty input	""	Usage: please input a number
invalid input: not a number	a	Usage: please input a number
sample input: even	2	Even
sample input: odd	5	Odd
sample input: negative even	-14	Even
sample input: negative odd	-27	Odd
