the index starts at 0

the index starts at 0 so i should retrieve item no. 6 right? keeps gettting a bummer! note

array.swift 
// Enter your code below

var arrayOfInts = [1,2,3,4,5,6]

arrayOfInts.append(7)

arrayOfInts += [8]

let value = arrayOfInts[6]

Indexes does start at 0, but that means that indexes are one less than you might expect them to be, not one above. Item 1 is at index 0, item 2 at index 1, item 3 at index 2, item 4 at index 3, item 5 at index 4.

So you have to use [4] to retrieve the fifth item, which is the item the task asks you to retrieve.
