How to Declare an Array in Go


How to Declare an Array in Go ?

Answer

In Go, you declare an array by specifying the type and length of the array.



✐ Examples

1 Declare an Array in Go

In this example,

  1. We declare an array named numbers of type [5]int and initialize it with some values.
  2. This creates a fixed-size array of integers.
  3. We print the array elements to the console.

Go Program

package main
import "fmt"
func main() {
    numbers := [5]int{1, 2, 3, 4, 5}
    fmt.Println("Array elements:", numbers)
}

Output

Array elements: [1 2 3 4 5]

2 Declare an Array of Strings

In this example,

  1. We declare an array named names of type [3]string and initialize it with some values.
  2. This creates a fixed-size array of strings.
  3. We print the array elements to the console.

Go Program

package main
import "fmt"
func main() {
    names := [3]string{"Alice", "Bob", "Charlie"}
    fmt.Println("Array elements:", names)
}

Output

Array elements: [Alice Bob Charlie]
