Try to debug this code. That will help you understand what is really happening.

It's not just a question ?...

I know the answer but there is something interesting ....

say to whom it is returning
the value..

Sorry if you feel my comment was harsh. I did not know that you knew the answer.

The problem is so trivial that I think a person who does no know the answer could have trouble using debugger -- I know that from my experience with others.

If you knew the answer -- sorry for suspecting you did not -- this is the different story. In this case -- why asking it? To share something interesting? But there is nothing interesting in it. It does not teach anything at any level. Redundant "if" (result of the check statically known), no sense -- is that interesting? I don't think so.

Sorry,

Solution 1

You've been asked this as a homework question. You can also just compile and run it to find the output and use the debugger to 'explain' it. We don't do homework for people who won't even try.
