Please read the FAQ 5.8 
(http://www.para****ft.com/c++-faq-lite/how-to-post.html#faq-5.8).
 Be a 
bit more specific as to "this isn't working".  What are your inputs? 
What is your output?  What is your *expected* output?

Note that from a cursory examination of the code, I could figure out 
what "isn't working" means, but still...

are you sure this is what you want?  The loop will only execute as long 
as the second statement is true.  So if a and b are different, well... 
nothing happens (which I assume is your complaint).
