Golang : Totalize or add-up an array or slice example

A simple example on how to totalize or add-up all the integer elements in a slice/array. Just use a for loop to add up the elements one-by-one.

Here you go!

 package main

 import (
 "fmt"
 )

 func main() {
 slice := []int{1, 2, 3, 4, 5, 6}

 total := 0

 for i := 0; i < len(slice); i++ {
 total = total + slice[i]
 }

 fmt.Println("Slice elements are : ", slice)
 fmt.Println("Elements add up to : ", total)

 }

Sample output:

Slice elements are : [1 2 3 4 5 6]

Elements add up to : 21
