Courses Plus Student 1,740 PointsHelp!! with getting the index numbers to get all iterations.
I don't know how to get all the iteration in the array.
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below
while counter < numbers.count {
counter += 1
sum = sum + numbers[0]
}

In this case, while the counter is less the number of elements in the array, you need to add the value of each and every element inside the array, to the sum.
You could also declare another variable, for example var index = 0
but then you'd have to increment that by 1 after the counter. Since you already have the counter, you can use the same for accessing the index of the array, every time it loops and updates by 1.
Hope this helps!
