Arrays have size - a fixed size, and cannot be resized (length is part of its type).
How to declare:
[size]type{}
To create an empty array:
var a [2]string
an array of 2 values of type string.
Can not mix types
func main() {
var a [2]int // if need just empty array
b := [2]string{"one"} // with some elements in the array
b[1] = "two"
a[0] = 0
a[1] = 1
fmt.Printf("The whole array: %v, %vn", a, b)
fmt.Printf("The 1st in array: %v, %vn", a[0], b[0])
fmt.Printf("The 2nd in array: %v, %vn", a[1], b[1])
fmt.Printf("Array type: %T, %Tn", a, b)
fmt.Printf("Array lengh: %v, %vn", len(a), len(b))
}
