Hey guys!

Long time no seen! Today I had a pleasure of going over **myprogrammingblog **emails, where many users have asked me to show solutions to different problems. Sorry for not being able to respond earlier, as I had whole bunch of things going on.

From now on, at least for a month, I will be regularly (read as 1 time in 1-2 days) posting some code examples for the problems you have asked me to take a look at. By the way, if you have any interesting problems, which you would like to share with me, please email me at: **myprogrammingblog@gmail.com** .

**Quick Update:**

I have opened myprogrammingblog Git repo, where I will be posting code examples discussed in this blog.

Repo URL is :

*https://github.com/myprogrammingblog/myprogrammingblog.com/*

Now, back to business.

One of the readers ( I am not posting names/nicknames since some people don’t like to be addressed publicly) asked me:

## How to check if a number is ODD or Even ?

To solve this problem I will use nice operator, available in most popular programming languages (e.g C/C++/Python/Java/PHP/JavaScript…you name it…) called **modulo (%) .**

**Modulo** – finds the remainder of the division. That’s exactly what we need!

We know that EVEN numbers are those that can be equally (read without a remainder) divided into two groups. By using modulo we can check if the number divided by two does not have a remainder, than it is an EVEN number, otherwise it is ODD.

Bored already ? Here is the code (since no specific language was required, I have used PHP):

<?php /* * Description: * This small function returns true if passed number * is divisible by two, false if not. * * @author: Anatoly Spektor */ function isEven($number) { $isEven = false; if (is_numeric ($number)) { if ( $number % 2 == 0) $isEven = true; } return $isEven; } ?>

In case you need** Unit Tests** for this function, they are available in the **repo**.

Thank you for sending me your questions!

Regards,

Anatoly

Hello,

Nice article. Thank you for sharing. I also shared a similar article on c programming. I posted a article to check whether a given number is odd or even using c program.

Here is the link for the article of c program to check given number even or odd.

Very effective and commonsensical solution, I remember when I first learned programming, this was one of the first problems given to us, at that time it appeared tough.
