in reply to spaces around the Arrow Operator (->)

There's no difference,
only a personal preference.

My personal preference is no spaces around the arrow, and I guess that's what the majority does, too, even in C++. At work, though, I'm often confronted with code that has a tab on the left hand side of the arrow, and a space on the right hand side.
