What can you replace "blah blah" with?
Well, three clauses, one that is executed before the bulk of the loop, one that tests if the loop should run, and one that gets executed after the loop.
So if you were to put
cout << "Hello "
in the first clause, and
cout << " !"
in the last, all you'd need to do is terminate the loop after the first iteration...
I'll leave the rest to you - it's your interview! :laugh:
