What is the intention of putting return values in parentheses in C/Objective-C?

c, objective-c, parentheses, return-value

Solution

At least as far as C is concerned, it makes no difference. The parens aren't necessary, but they don't change the meaning of the return statement. The grammar of the return statement is

return-statement:
    return expressionopt ;

and one of the productions of the expression non-terminal is a parenthesized-expression, or ( expression ).

Problem

I've come across some code that surrounds the return value from a method/function in parentheses. What does that do? The code I saw took an image, resized it and then returned it. ``` - (UIImage *)resizeImage:(UIImage *)image { // // some fascinating, but irrelevant, resizing code here // return (image); } ```
