Check if a number is even or odd ? Explained
How to check if a number is even or odd — but here's the twist — we focus on HOW TO THINK through the problem, not just write code.
We start from scratch and build step by step:
✅ Static — One fixed number
next
✅ Dynamic — User types any number
✅ Function — Make it reusable
✅ Advanced — Check many numbers with a loop
By the end, you'll understand the core logic: "Is the leftover 0?" — and you'll see how the same simple idea grows into powerful code.
This is perfect for beginners who want to build problem-solving skills, not just memorize code.
