in Go, an array is a numbered sequence of elements of a specific length
package main import ( "fmt" ) func main() { var a [5]int fmt.Println("emp: ", a) a[4] = 100 fmt.Println("set : ", a) fmt.Println("get : ", a) fmt.Println("len : ", len(a)) b := [5]int{1, 2, 3, 4, 5} fmt.Println("dcl : ", b) var twoD [2][3]int for i := 0; i < 2; i++ { for j := 0; j < 3; j++ { twoD[i][j] = i + j } } fmt.Println("2d: ", twoD) }
emp: [0 0 0 0 0] set : [0 0 0 0 100] get : [0 0 0 0 100] len : 5 dcl : [1 2 3 4 5] 2d: [[0 1 2] [1 2 3]]
