How to get Sub Array in Go ?

Answer

To get a sub-array in Go, you can use slicing on arrays or slices.

✐ Examples

1 Sub-array of Integer Slice

In this example,

We create an integer slice named numbers with some values.
We then use slicing to get a sub-array from index 2 to index 4 (exclusive).
Finally, we print the sub-array.

Go Program

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

Output

Sub-array: [3 4]

2 Sub-array of String Slice

In this example,

We create a string slice named colors with some values.
We then use slicing to get a sub-array from index 1 to index 3 (exclusive).
Finally, we print the sub-array.

Go Program

package main
import "fmt"
func main() {
    colors := []string{"red", "green", "blue", "yellow", "orange"}
    subArray := colors[1:3]
    fmt.Println("Sub-array:", subArray)
}

Output

Sub-array: [green blue]
