//
|
|
// Zig has some fun array operators.
|
|
//
|
|
// You can use '++' to concatenate two arrays:
|
|
//
|
|
// const a = [_]u8{ 1,2 };
|
|
// const b = [_]u8{ 3,4 };
|
|
// const c = a ++ b ++ [_]u8{ 5 }; // equals 1 2 3 4 5
|
|
//
|
|
// You can use '**' to repeat an array:
|
|
//
|
|
// const d = [_]u8{ 1,2,3 } ** 2; // equals 1 2 3 1 2 3
|
|
//
|
|
// Note that both '++' and '**' only operate on arrays while your
|
|
// program is _being compiled_. This special time is known in Zig
|
|
// parlance as "comptime" and we'll learn plenty more about that
|
|
// later.
|
|
//

|

const le = [_]u8{ 1, 3 };

const et = [_]u8{ 3, 7 };
|

|
|
// (Problem 1)
|
|
// Please set this array concatenating the two arrays above.
|
|
// It should result in: 1 3 3 7
|
|
const leet = ???;
|

// (Problem 2)

|
|
// have a little preview of Zig 'for' loops instead:
|
|
//
|
|
// for (<item array>) |item| { <do something with item> }
|
|
//
|

// Don't worry, we'll cover looping properly in upcoming

|
// lessons.
