need help Given an array of numbers, print out each number in the array using a while loop and the println statement.

while loops run as long as a condition is true.

to print out each item in the array, we can use a "counter" variable to index the array inside the loop and print out the item at the index.

after we print it, we can increment the counter, and the while loop will start over, and since the index "counter" keeps increasing, it will iterate over all the items in the array.

However, we need to use a condition for the while loop (if we dont it will loop infinitely)

We cant index anything thats out of the bounds of the array (an index that goes past the last item in the array), so we can check that the counter variable is less than the count of the array before looping:

let numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
// create a counter variable
var i = 0
// make sure the condition is true. we only want to use indexes within the bounds of the array
while i < numbers.count {

  // print the item at index i 
  println(numbers[i])
  // increase i by 1
  i += 1
  // loop starts over and the condition is checked once more. if its still true, loop again, if its false, break out of the loop. 

}

in the code above we create a counter variable called i and set it to 0. this will be the starting index.

next we loop while the counter is less than the count of the array. This ensures we dont go out of bounds of the array.

then we print the item at the ith index of the array

then increment i.

the loop then starts over, however i increases each time. so it starts at 0 and prints out the item at index 0, then loops again and prints the item at index 1, then loops again and prints the item at index 2 etc etc until the condition is no longer true. when i = 10, it is no longer less than the count of the array so it stops looping.

Yes I understood that it didn't print something to my printer lool.

I got it. Can you explain the purpose of the console?
