I created a super simple console c++ with just an infinite loop that prints a variable value. I change it per round as I'm planning to write another program to manipulate it. But first I tested with CE to see if I could find the value.

int testval = 1234;

I find it fine when I declare it globally outside main.

If I declare it inside main, I can't scan the value at all.

Is it because it's on the stack now? Or should I be able to scan it still?

I've been using CE a while (my own renamed/compiled 7.0 build), but it never occurred to me that this may be a thing. I suppose games (albeit few if any) with local variable use may be harder to target then.

Does your main code modify the testval variable? If not, the compiler may just remove it or replace it with the value.

e.g: a compiler may rewrite this code:

Started to suspect compiler optimization, thanks for verifying. I got it scannable now.

Thanks.
