The Train

Imagine a train with numbered compartments:

🚂 [Car 0] [Car 1] [Car 2] [Car 3] [Car 4]

Each car has a number (starting from 0!) and can hold one thing.

Arrays are trains for your data!

Full deep‑dive with code examples

In Code

fruits = ["apple", "banana", "cherry", "date"]

Index:    0         1          2        3
       ["apple", "banana", "cherry", "date"]

To get banana: fruits[1] (index 1, the second item)

Why Start at 0?

Tradition from early computers! Just remember:

• First item = index 0
• Second item = index 1
• Third item = index 2

What Can You Do?

In One Sentence

Arrays store multiple items in a numbered list, like numbered train compartments in a row.
