//

// Let's learn some array basics. Arrays literals are declared with:
|
|
//
|
|
// [size]<type>{ values };
|
|
//
|
|
// When Zig can infer the size of the array, you can use '_' for the
|
|
// size like so:
|
|
//
|
|
// [_]<type>{ values };
|
|
//
|

const some_primes = [_]u8{ 2, 3, 5, 7, 11, 13, 17, 19 };
|
|
|
|
// Array values are accessed using square bracket '[]' notation.
|
|
//
|
|
// (Note that when Zig can infer the type (u8 in this case) of a
|
|
// value, we don't have to manually specify it.)

|
const fourth = ???;

// Use '.len' to get the length of the array:
|

const length = some_primes.???;
