Memory City: Understanding Addresses

Think of computer memory like a city with numbered houses. Each 'house' (memory location) has a unique address and can store data. Just like you can write down a house address on paper, you can store memory addresses in variables called pointers.

Visual Analogy:

🏠 Memory = City of numbered houses
📍 Address = House number (like 0x1000)
📋 Pointer = Piece of paper with house address written on it

🤔 Before you experiment, predict: What do you think will happen?

Memory City

💡 Tip: Each block represents 4 bytes of memory. Addresses increase from top-left to bottom-right.
