possible but I am not able to find out.

If a variable is local to a function other than main,
then it may or may not have the same address,
each time the function is called during the run of the program.

On some (many?) architectures, even globals, statics, and main()'s locals will vary across runs. In the case of recursive functions, different instances of the same locals may exist in several places.

The only decent answers are "find out with the & operator at runtime" or "use a debugger".
