Here's my program and here are the outputs:

921 - nine hundred twenty one
912 - nine hundred twelve two
902 - nine hundred two

Now, I can't figure out how I can display 912 as nine hundred twelve and not nine hundred twelve TWO. That's what happens everytime I input numbers with 11 to 19 as the last two digits.

More examples:
911 - nine hundred eleven ONE
319 - three hundred nineteen NINE
717 - seven hundred seventeen SEVEN
