In this example, we will show you how to iterate over an array in Go with an example.

With for loops, we can iterate over array elements in Go.

Go - Array Iteration Example

The example uses three for loop forms to iterate over an array of programming languages.

package main

import "fmt"

func main() {

    progLangs := []string{ "C", "C++", "Java", "Python", "Go" }

    for i := 0; i < len(progLangs); i++ {

        fmt.Println(progLangs[i])
    }

    for idx, e := range progLangs {

        fmt.Println(idx, "=>", e)
    }

    j := 0

    for range progLangs {

        fmt.Println(progLangs[j])
        j++
    }
}

Output:

C
C++
Java
Python
Go
0 => C
1 => C++
2 => Java
3 => Python
4 => Go
C
C++
Java
Python
Go
