A collection of Bad Code Smells in a Catalog form for Developers & Researchers. Code Smell is a typical bad code implementation, and learning these concepts immiedietly makes you a better developer!
Only the visibility is local. The data is still global state. You can call that function from anywhere and it will use the same state. That’s what global state means.
Some of the biggest issues with global state are that is makes testing difficult and it makes concurrent code more error-prone. Both of those are still true for locally scoped static variables.
I don’t need to Google anything. I have 30 years experience writing C & C++.
Yes it is.

Again, it’s an easy refactor to make it not global. There are cases where that extra abstraction work simply does not add value.
With your background, you should know that
I have enough experience to know that making global state non-global is usually anything but easy.
Damn, suppose I won’t just pass it as a pointer from the call site. That’d be so difficult to add an int to a struct
