Insert space between void function?

Hi-
I'm new to Arduino. When writing a void function, e.g.,

void setup()

Should I insert a blank space between the parentheses? Or does it not make a difference whether you insert one or not? Thanks.

does not make a difference

Thanks!

In fact, if you do CTRL-T to autoformat your code every once in a while it can help clean up things like that, and also help you to find
missing ;'s, mismatched ( )s and { }s, undeclared variable names, etc.
The message may not be clear, but you'll get some kind of notification 8)

Very cool. Thanks for that tip!
