Programming logic: whether a Number is Odd or Even

Here I’ll show you how to check whether a number is odd or even using PHP, Python, and JavaScript.

Programming logic to check whether a number is odd or even

theNumber % 2 == 0

If a number is divided by 2 and the remainder is 0, then the number is an even number otherwise the number is an odd number.

Modulo operator (%)

In most of the programming language the modulo operator (%) is used to compute the remainder.

After getting the remainder, we will check whether the remainder is equal to 0 or not, If yes, then it is an even number, otherwise it is an odd number.

<?php
$num = 6;

if ($num % 2 === 0) {
    echo "$num is Even";
} else {
    echo "$num is Odd";
}

const num = 6;

if (num % 2 === 0) {
  console.log(num + " is Even");
} else {
  console.log(num + " is Odd");

num = 6

if(num % 2 == 0):
    print("{0} is Even".format(num))
else:
    print("{0} is Odd".format(num))
