786 PointsWhile Loops Code Challenge
I dontβt understand how to solve the second part of the while loop code Challenge
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 + newValue
}

bit was only meant as an example. That's not a solution.
You want to add each number from the numbers
array using the counter
as the index. So numbers[0]
(when the counter is 0) would be the first value in the numbers array, 2
. This is when you add it to the sum
variable using that sum += newValue
demonstration in the challenge description. It would look like sum += numbers[counter]
in this case.
Also, make sure to have the counter incrementing afterward because you would be skipping over the first index value if not.
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
while counter < numbers.count {
sum += numbers[counter]
counter += 1
}
