array in Go
The type [n]T is an array of n values of type T. An array's length is part of its type, so arrays cannot be resized. By default, the elements of a new array variable are initially set to the zero value for the element type, which is 0 for numbers. We can use an array literal to initialize an array with a list of values: ``` package main import "fmt" func main() { var a [3]int = [3]int{1, 2, 3} fmt.Println(len(a)) fmt.Println(a) } ```
