    So you don't actually write any of your own code? That's sad, and means you're not learning much.
    can anybody can explain it to me please
    Tell us first what you think the code does and ask for correction/help understanding the parts you've gotten wrong.

    Hi,
    If you want to understand the code just trace the program statement by statement from main() using a pen and paper.
    You shall know what is happening.
