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
