Basic Arrays

Snippet

Basic Arrays

Arrays in Go have a fixed length that is part of their type. Once defined, their size cannot change.

snippet.go
go
package main
 
import "fmt"
 
func main() {
    var ids [3]int
    ids[0] = 101
    ids[1] = 102
    ids[2] = 103
 
    names := [2]string{"Alice", "Bob"}
    fmt.Println(ids, names)
}

Breakdown

var ids [3]int

Declares an array that can hold exactly 3 integers.

ids[0] = 101

Assigns a value to the first index (zero-based).

[2]string{"Alice", "Bob"}

Short-hand syntax to declare and initialize an array simultaneously.
