First of all, I would like to thank you for understanding my problem and giving
me advise to read Ritchie's book and "The Art of Computer programming". I will
def. read these books to improve my knowledge for programming logic.

Well, Hari, you know Nico is very right that your way was quite discouraging to
answer like that. You really need to work on your behaviour with others. Because
if you want to be liked by others then you should not laugh at others, instead
guide them to learn the right things.

Well, I am not a 14-year old boy, who will be discouraged with such an answer.
But, if there would be someone else of younger age, it would be very
discouraging for him.

Well, I wish you luck for changing your attitude towards others and try to be
and encouraging person.
