Domain: Programming Fundamentals
🎯 Motivation
You need a way to store information that can change while your program runs, like a player’s score in a game.
📋 Concrete Example
In Python: score = 0 stores the number 0. Later, score = score + 10 updates it.
🔗 Analogy
A labelled box on a shelf - you write score on the box and put a number inside. You can swap the number anytime.
