I think in C++, 'C' is a constant not a variable. (sic)
Yes, you're right, 'C' isn't a variable. Moreover, judging by the quotation marks, I'm assuming you're referring to a character literal. If this is the case, then yes, literals are constant, neither do they have an address, just so you know, of course.
