In this program, we will learn to code the Kotlin Program to Check Whether a Number is Even or Odd. Let’s understand more about even and odd numbers then we will see the logic to check whether a number is even or odd in Kotlin Programming Language.
Even Numbers
A whole number that can be divided by 2 into two whole numbers is called an even number. For example, 2, 4, 6, 8, 10, etc.
Odd Numbers
A whole number that cannot be divided by 2 into two whole numbers is called an even number. For example, 1, 3, 5, 7, 9, etc.
Now, let’s see the Kotlin Program to Check Whether a Number is Even or Odd.
Kotlin Program to Check Whether a Number is Even or Odd
//Kotlin Program to Check Whether a Number is Even or Odd
import java.util.Scanner;
fun main() {
var sc = Scanner(System.`in`);
println("Enter a number: ");
var num = sc.nextInt();
if(num % 2 == 0){
println("$num is an Even Number");
}
else{
println("$num is an Odd Number");
}
}
Output
Enter a number: 77
77 is an Odd NumberEnter a number: 18
18 is an Even NumberHow Does This Program Work?
var sc = Scanner(System.`in`);
println("Enter a number ");
var num = sc.nextInt();
In this program, first, we have taken the input of the number from the user, using the Scanner Class of Java. We import the Scanner Class using import java.util.Scanner;
if(num % 2 == 0){
println("$num is an Even Number");
}
else{
println("$num is an Odd Number");
}
Then, we have used the if-else to check whether the number is fully divisible by 2 or not.
If the remainder is 0 when the given number is divided by 2 then it is an Even Number otherwise it is an Odd Number. So, to check the remainder we use the modulo operator i.e. “%”.
This is the Kotlin Program to Check Whether a Number is Even or Odd.
