How to reverse the elements of array in Golang?

Problem Solution:

In this program, we will create an integer array and then assign the array elements in reverse order into another array. After that, we will print reversed array on the console screen.

Program/Source Code:

The source code to reverse an integer array is given below. The given program is compiled and executed successfully.

Golang code to reverse the elements of array

// Golang program to reverse an integer array

package main

import "fmt"

func main() {

	var rev_arr [6]int
	arr := [...]int{0, 1, 2, 3, 4, 5}

	var j int = 5
	for i := 0; i <= 5; i++ {
		rev_arr[j] = arr[i]
		j = j - 1
	}

	fmt.Println("Reversed array: ")
	for i := 0; i <= 5; i++ {
		fmt.Printf("%d ", rev_arr[i])
	}
}

Output:

Reversed array:
5 4 3 2 1 0

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In the main() function, we created an array arr initialized with few elements. Then we copy the elements of arr into rev_arr in reverse order. After that, we printed the elements of reversed array rev_arr on the console screen.
