How to Iterate Over an Array in Go ?

Answer

To iterate over an array in Go, you can use a for loop or range-based iteration.

✐ Examples

1 Iterate Over Integer Array with for Loop

In this example,

We create an integer array named numbers with some values.
We use a for loop to iterate over each element of the array and print the elements.

Go Program

package main
import "fmt"
func main() {
    numbers := []int{1, 2, 3, 4, 5}
    for i := 0; i < len(numbers); i++ {
        fmt.Println(numbers[i])
    }
}

Output

2 Iterate Over String Array with Range-Based Loop

In this example,

We create a string array named fruits with some values.
We use a range-based loop to iterate over each element of the array and print the elements.

Go Program

package main
import "fmt"
func main() {
    fruits := []string{"apple", "banana", "cherry"}
    for _, fruit := range fruits {
        fmt.Println(fruit)
    }
}

Output

apple
banana
cherry
