Error in video?

Hi!

If we set the 'remainingInvaders' variable to 0 in the while loop before the second foreach loop than the while loop will exit, so the foreach loop never gets executed where we count the invaders still moving. There is something wrong... am I right?

Thanks for your help!

Setting the 'remainingInvaders' variable to 0 does not cause the loop to exit. The while loop only checks that value when the loop repeats, which will only happen after the foreach loop runs and has a chance to raise the count back up.
