Overview

An array is a numbered sequence of elements, of a single type, and with a fixed length.

Declaration

var a [5]int

A declaration without explicit initialization initializes the array with the type's zero value.

Type inference and initialization declaration:

a := [5]int{1, 2, 3, 4, 5}

Array Literals

a := [5]int{1, 2, 3, 4, 5}
a := [5]int{
        1, 
        2, 
        3, 
        4, 
        5,
   }

The extra trailing comma is required when the elements are specified on separate lines, but not when they're specified in a single line.
