Well, well, afraid you're going to be asked to explain your code to your instructor? Or do you have to turn in a written explanation/description of it with the code?

In any case, if you had done your assignment, rather than copying it, you would probably understand it.

P.S. Whether any of the above is true, or not, don't bother protesting, as nobody here is going to believe it. We see far to many "do my assignment for me" requests to believe that you "got this from a friend" for anything other than a homework assignment.

Try to give a proper description to the thread.

Don't put "Please Help" as the thread.

Obviously everybody here are going to help you, if you show your effort.

And if you are not putting any effort no body will help you obviously.

So try to put the proper Title for the Threads you post in future.
