// 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 std = @import("std");
|
||||
|
||||
pub fn main() void {
|
||||
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 first = some_primes[0];
|
||||
|
||||
// Looks like we need to complete this expression:
|
||||
const fourth = ???;
|
||||
|
||||
// Use '.len' to get the length of the array:
|
||||
const length = some_primes.???;
|
||||
|
||||
std.debug.print("First: {}, Fourth: {}, Length: {}\n",
|
||||
.{first, fourth, length});
|

}
