How to get the length of a array in Go

In this tutorial we are going to learn, how to find out the length of a array in Go language.

The length of an array means total number of elements present in a array.

Getting the array length

To get the length of a array, we can use the built in len() function in Go.

The len() function takes the array as an argument and returns the number of elements in a array.

Here is an example, that gets the length of a cars array :

package main
import "fmt"

func main() {
    cars := [4]string{"bmw","benz","audi","skoda"}
    length := len(cars)
    fmt.Println(length)

Output:

4

Note: In Go arrays are fixed sizes, once we create an array it can’t be changed later.
