You want to write a program that will check if a number is even or odd.
We know that a number is even if it is completely divide by 2.
The modulus arithmetic operator can tell you the reminder when you divide a number by another number. To test an even number, we’ll divide it by 2. If it is completely divided by 2 (or in other words, it is an even number), it will returns 0. Otherwise, it is an odd number. See it in code-
<?php $number = 229; echo ($number%2 == 0) ? $number." is an even number." : $number." is an odd number."; ?>
229 is an odd number.
How it works:
After dividing 229 by 2, the reminder is 1, so it is an odd number.
