main() Function
I would guess is similar to an executable file within the code. I’m not sure if the question is about the ( ) themselves or what a “main function” is. The words main function make me assume it is the command that is to be executed. Other parts of the code can be more like adjectives or pronouns. If we are talking about the ( ) themselves within the code. And maybe those characters are described as main functions. I will venture to guess that parenthesis separate a function from the surrounding code. So again, maybe it is to separate an actual command from other pieces of code which could be considered modifiers.
That’s my first guess on what the heck is going on so far! LoL… I’m sure I’m way off but lets see what the truth is!
Oh were we supposed to guess after LOOKING at the example code??
