How to check if Two Arrays are Equal in Go - Step by Step Examples

How to check if Two Arrays are Equal in Go ?

Answer

To check if two arrays are equal in Go, you can use a loop to compare each element for arrays with the same elements and use the reflect.DeepEqual function for arrays with different elements.

✐ Examples

1 Arrays with Same Elements

In this example,

We create two arrays named arr1 and arr2 with the same elements.
We then use a loop to compare each element of both arrays and store the result in the variable equal1.
If all elements are equal, equal1 is set to true; otherwise, it's set to false.
Finally, we print the value of equal1 to the console.

Go Program

package main
import (
	"fmt"
)
func main() {
	arr1 := []int{1, 2, 3}
	arr2 := []int{1, 2, 3}
	equal1 := true
	for i := range arr1 {
		if arr1[i] != arr2[i] {
			equal1 = false
			break
		}
	}
	fmt.Println("Arrays are equal:", equal1)
}

Output

Arrays are equal: true

2 Arrays with Different Elements

In this example,

We create two arrays named arr3 and arr4 with different elements.
We then use the reflect.DeepEqual function to check if the arrays are equal and store the result in the variable equal2.
The reflect.DeepEqual function compares two interface{} values and returns true if they are deeply equal.
Finally, we print the value of equal2 to the console.

Go Program

package main
import (
	"fmt"
	"reflect"
)
func main() {
	arr3 := []int{1, 2, 3}
	arr4 := []int{3, 2, 1}
	equal2 := reflect.DeepEqual(arr3, arr4)
	fmt.Println("Arrays are equal:", equal2)
}

Output

Arrays are equal: false
