4,869 PointsSumming process not working
Hi, I cant figur out why my answer is not the correct here.
Shouldn't the while loop work properly (and sum the variables of the numbers array)?
let numbers = [1,2,3,4,5,6] var sum = 0 var counter = 0
while counter <= numbers.count { sum += numbers[counter] counter += 1 }
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below
while counter <= numbers.count
{
sum += numbers[counter]
counter += 1
}

You don't want counter
to be equal to numbers.count
as that'll exceed the length of the array. So, loop while
counter
is less than numbers.count
. Just delete the equals sign from your <=
and your code is fine!
With it in there, you would try to access numbers[7]
which would throw an out of bounds exception.
Steve.
