An array stores a fixed number of values of the same type, laid out one after another in a single block of memory. 📦

In Zig the length is part of the array's type and is decided at compile time. It can never grow or shrink once declared.

You write the count in square brackets, then the element type. This [3]i32 holds exactly three signed integers.

Use an underscore for the size and Zig infers it from the values you list. Here [_]i32 becomes a three-element array.

Reach an element by its index in square brackets. Indices begin at 0, so nums[0] is the very first value.

Every array exposes its size through the len field. It is known at compile time and never changes.

Reading past the end is caught for you. In safe builds an out-of-bounds index triggers a runtime panic instead of silent corruption.

Repeat a single element across the whole array using the ** operator. This makes five zeros without typing each one.

Assigning one array to another copies every element. The two arrays are independent, so changing one leaves the other untouched.

Declare the array with var to change elements later. Then assign through an index to update a single slot.

Elements can be any type, even other arrays. A [2][3]i32 is a small grid: two rows of three integers each.

You declared const nums = [_]i32{ 1, 2, 3 }. What does nums.len evaluate to?

A fixed-size array packs same-type values together: length is part of the type, indices start at 0, and access stays bounds-checked. 🎯
