Answer :

frdelrosario Thank you for indirectly calling me stupid. I’ve received very kind and constructive help regarding C++ programming in the past on Fluther. I’m pretty sure Fluther is more than a web forum to debate ethereal questions. Looking through your answer profile, you might want to chill out a bit and stop attacking people for asking what they don’t know on a site constructed for that very purpose. Perhaps I don’t know how to phrase this elaborate question into a Google query. Just chill out a bit, go take a walk, breathe the air of life – you can think then about how we’re all not as smart as you for asking questions to which you, in your almighty academic god status, already know the answer, yet are too inconvenienced to divulge without insult.
