Interview Questions - Teaching, !Yet Another For Loop

Q: How would you teach loops to someone who is new to programming?

After the likely:

var loopAction =
  (i) => { Console.WriteLine("Current Value: {0}", i); };
for(var i = 0; i <= 10; i++) {
  loopAction(i);
}

Prompt for a loop that uses a non-numerical loop-control variable.  This should give the developer the opportunity to show that they truly understand the nuts&bolts of what we do.
