Volatile variable

Question

Where is a volatile variable stored in the program memory(in which section) ?

Answer 1

There's no reason for a volatile variable to be stored in any "special" section of memory. It is normally stored together with any other variables, including non-volatile ones. If some compiler decides to store volatile variables in some special section of memory - there's nothing to prevent it from doing so. But at the language level there's absolutely no reason for this.

Why are you asking such a question? What made you think that it should be stored in some special section of memory?
