I\'m an old (but not too old) Java programmer, that decided to learn C++. But I have seen that much of C++ programming style, is... well, just damn ugly!
All that stuff
Find a style that works for you, just like everyone else did. Nobody is forcing you to use one of the "ugly" styles, unless it's your employer enforcing a guidelines document. ;-)
Though keep in mind that placing member function definitions inside the class as opposed to outside has different semantics. When you define a member function inside the class, it's implicitly inline, for better or worse.
