The temptation is always there

Is it really tempting for people? They've given me too many headaches when I've had to reformat or add functionality to files.

Unless it's a simple single use script that fit on the computer screen, I don't feel like global variables would ever be tempting, unless it's for constants.

Just create a global object and stuff your variable in there. Now you have a global singleton and that's not a purely bad practice :D

Obligatory, mutable global variables are evil.

You can do better, define intergalactic variables that share the same memory location across multiple programs so you can seamlessly pass variables from one to the next.

Singletons:

Me: O_O;

Is it an orgy if multiple global variables are used in a multi threaded code?

I've once had a course involving programming and the lecturer rewrote the code, which we were usually using at our institute, making ALL variables global. - Yes, also each and every loop counter and iterator. 🤪

"But what if I put the whole program into a class and then made it a class wide variable?"

I am not a programmer who knows how to program. I know this because global variables are how I fix most the issue I run into, but are constantly told this wrong.

I asked stable diffusion for a photo-realistic version of this image. This isn't what I had in mind

Me putting everything in 'public:'

Exhibitionist Devs be like.

the meme is spreading

Our Father, who art in Microsoft HQ,

hallowed be thy naming conventions;

thy architecture;

thy will be done;

on earth as it is in Linus Tech Tips.

Give us this day our daily StackOverflow.

And forgive us our 'sploits,

as we forgive those who trespass against our user stories.

And lead us not into temptation;

but deliver us from a thicket of global variables.

For thine is the irritating project manager, the power and the glory,

for ever and ever.

Or at least 7 years until obsolescence.

Amen.

Nothing wrong with global variables.

If anyone asks just say it's the singleton pattern.

This, but with not making unit tests instead of global variables.

accurate

Nowadays they call it global state lol

Have you tried #ifdef'd global variables? Should definitely make things easier to read

Ironically, a guy named SingletonSean showed me how to avoid singletons.
