Warm Up · Function, if-else
Even or Odd Number
Problem Statement
Write a function that accepts a number and checks whether it is Even or Odd. If the number is divisible by 2, it is an Even number; otherwise, it is an Odd number. Test the function with inputs 18 and 5.
Example
Input: 18, then 5
Process: 18 % 2 = 0 → Even; 5 % 2 = 1 → Odd
Output: Even Number, Odd Number
Approach
- Create a function that takes a number.
- If
number % 2 === 0, it is "Even". - Otherwise, it is "Odd".

"Even Number"4No → odd
"Odd Number"Explanation
- Accept the input number in the function.
- Check if the number modulo 2 equals 0 -
%gives the remainder after division. - If yes, print or return "Even".
- Otherwise, print or return "Odd".
- Test the function with different numbers (like 18 and 5) to verify correctness.
