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

Hey, just answered this in another thread so I hope you don't mind it's a copy / paste job!

So in order to iterate through our array, we need to create a counter which will also act as the index that will keep track of how many times we've looped.

var index = 0

Next step is to build the while loop. In this task, we want to loop over all the values. We can use count method of the array in order to make sure we only loop as many times as needed.

while index < nameOfArray.count {

}

If you ran this, the loop would run forever. To fix this we need to include the index and increment it by 1.

while index < nameOfArray.count {

   index++
}

Finally add your print statement inside the loop - use the index to target the correct value within the array.

while index < nameOfArray.count {

   println( nameOfArray[index] )

   index++
}
