We also learned about reading values from an array. Retrieve the 5th item (remember array indexes start at 0) and assign

Question

help please. i think i am close but i do not know where is the error.
```array.swift
// Enter your code below
var arrayOfInts = [1, 2, 3, 4, 5, 6]
arrayOfInts.append(7)
arrayOfInts += [8]
arrayOfInts[6]
let value = arrayOfInts[6]
```

Because the 5th element in the array is 5 yet indexes start at zero so to retrieve it, it is 4
```Swift
var arrayOfInts = [1,2,3,4,5,6]
arrayOfInts.append(7)
arrayOfInts += [8]
let value = arrayOfInts[4]
```
