822 Pointshow do you retrieve the value from an array
I still can't find how to solve this problem despite getting help
let numbers = [2,8,1,16,4,3,9]
var sum = 0
var counter = 0
// Enter your code below
while counter < numbers.count{
sum = sum + numbers.count
counter++
}
sum = sum + 7

16,009 PointsHey Kehinde,
In your while loop, you are constantly adding the same, constant number numbers.count
, which is 7. The challenge is asking you to add the numbers in the numbers
array using the loop. To do this, you must access the numbers in the numbers
array by using numbers[counter]
since you have a variable counter
to keep track of where you are in the array. The last line in your code is not needed, and everything should look something like this:
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++
}
Hope this helps, Rodrigo
