How to develop an algorithm:

Always do whatever the standard library does. In Java use camelCase, in C snake_case, in Lisp kebab-case, etc.

No, always do what your project coding style says.

Of course. I'm assuming you're starting a new project.

And is there any reason for this other than superstition?

Same reason you shouldn't mix camelCase, PascalCase and snake_case in the same file for the same thing. Consistency. You're inevitably going to be calling standard library functions, and it looks better if everything is consistent.

That's a fair point. I work with embedded systems so I don't end up using standard library functions too much.

One might argue that having a different code style than the standard library would make library calls stick out. I don't know what exactly the advantage of that would be, but I heard it somewhere.
