I have the following use case , array of integers
vector<int> containing elements 123 345 678 890 555 ... pos 0 1 2 3 4
Based on the bits representation I receive for e.g
101 then return 123 678 (Elements of the array with its position bits set)...

So you have to go in reverse looking at the array to select the correct elements.
Sizeof(bits) ; i++) if(bit[i] == '1') filtered.push_back(myvector[i]); return filtered
OK, You can do corresponds to position "3" in the array).

I was looking at some example C# code, and noticed that one example wrapped the return in ()'s.
I've always just done:
return myRV;
Is there a difference doing:
return (myRV);

Which are the advantages/drawbacks of both approaches?
return items.Select(item => DoSomething(item));
versus
foreach(var item in items) { yield return DoSomething(item); }

Another simple example:
if (wpa_s->mlme.ssid_len == 0) return -EINVAL;
Why the unary minus? Is this (usually) done for functions that return >0 on success and <(=)0 on failure, or is there some other reason?
