Trying to satisfy the code challenge: Working with While ... While Loops. Here is my code:

let numbers = [2,8,1,16,4,3,9] var sum: Int = 0 var counter: Int = 0 while counter < numbers.count { sum = sum + numbers[counter] counter++ } print (sum)

Sorry, My paste did not fully get transferred. I will try again.

Got the challenge to accept my code! Apparently, as with the problem here, I must have had some keystrokes invisible to the eye in my cut-n-paste. I manually typed my code into the challenge and it was happy.

Another attemp at pasting my code:

let numbers = [2,8,1,16,4,3,9]

var sum: Int = 0

var counter: Int = 0

while counter < numbers.count {

```sum = sum + numbers[counter]

counter++
```

}

print (sum)

OK . . . third attempt to put my code in. Paste leaving lines out. Suppose I must enter each line manually:

let numbers = [2,8,1,16,4,3,9] var sum: Int = 0 var counter: Int =0 while counter < numbers.count { sum = sum + numbers[counter] counter++ } print(sum)

For some reason the conditional did not show up again in the while statement. This editor does not appear to like the "less than symbol" so I will not actually use it, instead I will put the symbols in quotes.

I have the following: while counter "less than symbol" numbers.count then the "left curly bracket" sum = sum + numbers[counter] counter++ "right curly bracket" print(sum)
