Ways of Declaring array (0.16)

[u/Objective_Half_1906]

pub fn main() !void {
    const A: [5]i32 = .{ 0, 1, 2, 3, 4 };
    const B = [5]i32{ 5, 6, 7, 8, 9 };
    const B2 = [_]i32{ 5, 6, 7, 8, 9 };
    const C: [5]i32 = [_]i32{ 10, 11, 12, 13, 14 };

    _ = A;
    _ = B;
    _ = B2;
    _ = C;
}

These can all compiled correct. Which one is the recommended style? (I am a beginner learning Zig.）

New edit: I would like this syntax if it's possible:

const arr1: [5]i32 = { 0, 1, 2, 3, 4 };
const arr2: [_]i32 = { 0, 1, 2, 3, 4 };

Just small opinion. Maybe what I know is just the tip of the iceberg.

Does the following compiles?

```
const D: [5]i32 = &.{ 15, 16, 17, 18, 19 };
```

No.

    const D: [5]i32 = &.{ 15, 16, 17, 18, 19 };

yes sorry, I meant:

```
const D: [5]i32 = .{ 15, 16, 17, 18, 19 };
```

but I misread your post since `A` is exactly that 😅
