[Icc-avr] Variables declared in main() and the stack

[Kevin Davis]

I'm learning more about pointers and their relation to the heap and
stack and was wondering:

 

Does it make sense (if scope is not an issue) to make variables that
will only be used in main() global rather than use up stack space with
them?

 

Just curious as to any rules-of-thumb with regards to this (if there are
any). If this question makes no sense let me know as well but from what
I've learned the variables declared in main() are put on the stack and
would remain there for the program's duration.

 

Thanks,

Kevin
