Fixed-Size Array
Domain: Data Structures
🎯 Motivation
Sometimes you know exactly how many items you will store and want the speed and memory efficiency of a fixed buffer.
📋 Concrete Example
In C: int seats[6] = {0,0,0,0,0,0}; reserves exactly 6 integer slots. You cannot add a 7th seat.
🔗 Analogy
A six-seater car. You cannot magically add a seventh seat. If you need more passengers, you need a bigger vehicle.
