My coding style changes everytime I change my employer. Every company has their own flavor of coding style. When it comes to my personal project I tend to follow the style that I am following at work. So, different projects of mine followed different coding styles depends on when I did it.
To be consistent across my personal projects, I am writing this style guide, for myself, collected from different standards (Google, MISRA, etc.) according to my likings.
Doesn’t matter what you follow, be consistent.
You can find the guide on GitHub.
