Write a counting program that stops after ten iterations.
Use a Do Until loop with a maximum of 10 iterations. You can do the condition test at the start or end of the loop -- whichever seems most natural to you.
Check input validity, and test your loop using extreme values. Be sure it works if the user enters 0 or 1 letters or the maximum number allowed by the program.
Turn in a screen shot of program running along with its listing.
