How could I know that "" + c and "" + (int)c are not the same. I mean, how do I know that (int)c will return 97, and not, for example, 96 or 98? Should I know the exact integer, or should I only know that there is a difference for the exam?
I not only use all the brains that I have, but all that I can borrow. [Laurence J. Peter]
