Arrays

Retrieve the 5th item and assign the result to a constant named value.

I have no idea what i am doing wrong.

arrays.swift 
// Enter your code below
var arrayOfInts = [1,2,3,4,5,6]
arrayOfInts.append(7)
arrayOfInts += [8]
let value = arrayOfInts[]

You're doing brilliantly! You got 3 out of 4 steps correct. And I'm of the opinion that the first 3 steps were the most difficult. Now all you have to do is go into that array and get out the fifth element. Which in your case is 5. Most people start counting from 1. Computers and programming languages (at least most of them) start counting from 0. So if you need the fifth element, you have to look at the array at the index of 4. Index 0 has a 1. Index 1 has a 2 etc etc. 

// Enter your code below
var arrayOfInts = [1,2,3,4,5,6]
arrayOfInts.append(7)
arrayOfInts += [8]
let value = arrayOfInts[4]

This is your code modified by one number! Hope this helps and hang in there :smiley:
