It's hard to say about that, since there is ... which can contain anything (like for example another opening { ).

It's a good practice to always use braces with if / else even if it's just one line in them.




I don't think you are right. Regardless if what is after that contained in the `...` wouldn't matter. A lone `{` or `}` would be a syntax error.


As I said, it wouldn't be a syntax error if ... contained the matching { somewhere inside.

That lone } which seemingly belongs to if in this case would be closing the function.


They are talking about the } after the return, not the one after the ... i.e. else return(1); }


Yes, that's what I understood. That } after return matches to the function opening {. So it's correct syntactically, but is wrong according to intention.
