how to make an array in go code example

Example 1: go arrays

var a [10]int // declare an int array with length 10. Array length is part of the type!
a[3] = 42     // set elements
i := a[3]     // read elements

// declare and initialize
var a = [2]int{1, 2}
a := [2]int{1, 2} //shorthand
a := [...]int{1, 2} // elipsis -> Compiler figures out array length

Example 2: how to declare array in golang

package main
import "fmt"

func main() {
	var x [5]int // An array of 5 integers

	x[0] = 100
	x[1] = 101
	x[3] = 103
	x[4] = 105

	fmt.Printf("x[0] = %d, x[1] = %d, x[2] = %d\n", x[0], x[1], x[2])
	fmt.Println("x = ", x)
}
