Array
Domain: Programming Fundamentals
🎯 Motivation
When performance matters (games, science, AI), a fixed-size array stores data more efficiently than a list.
📋 Concrete Example
In C: int scores[5] = {10, 20, 30, 40, 50};. All elements must be the same type and the size is fixed.
🔗 Analogy
A tray of labelled compartments - each slot is exactly the same size, lined up in a row, and you can’t add more slots.
