## Algorithm

1. Input: Accept a number as input.

2. Check Remainder: Divide the input number by 2.

3. Check for Zero Remainder:

• If the remainder is zero, the number is even.
• If the remainder is not zero, the number is odd.
4. Output:

• Display or return the result indicating whether the number is odd or even.

## Code Examples

### #1 Code Example- Using if...else

Code - Javascript Programming

// program to check if the number is even or odd
// take input from the user
const number = prompt("Enter a number: ");

//check if the number is even
if(number % 2 == 0) {
console.log("The number is even.");
}

// if the number is odd
else {
console.log("The number is odd.");
}
Copy The Code &

Output

cmd
Enter a number: 27
The number is odd.

### #2 Code Example- Using Ternary Operator

Code - Javascript Programming

// program to check if the number is even or odd
// take input from the user
const number = prompt("Enter a number: ");

// ternary operator
const result = (number % 2  == 0) ? "even" : "odd";

// display the result
console.log(`The number is \${result}.`);
Copy The Code &

Output

cmd
Enter a number: 5
The number is odd.
