Difference between return() and simple return

Question

I am just coding and a simple idea (obviously question) comes to my mind that if I have a function like :

int fun1(int p){
  return(p); 
}

and I have a function like this:

int fun1(int p){
  return p; ==> absence of parenthesis
}

so what the difference between those 2?

There's no difference at all, it's just an old convention. http://stackoverflow.com/questions/161879/parenthesis-surrounding-return-values — Solorzano Jose, Feb 11 '13 at 06:27
First one with `()` just adds clutter. Majority of Java is coded without unnecessary parentheses. — Steve Kuo, Feb 11 '13 at 06:48

No difference. You can decide to use parens if it makes things clearer.

There is zero difference. It's just a redundant way of writing the return-expression.

It dates from some very bad old days of C programming when some people wanted to make return statements look like function calls, or if/while statements.

The fallacy in that was that they aren't function calls or if/while statements.
