> Distinguishing private data members from local variables and formal parameters is useful. It creates a distinct "namespace" from local variable and formal parameter names. How to mark them is purely subjective. Some use the "m_" prefix, popularized by MFC and MSVC code generators, but I find that to be too much of a wart on the name. Some use "this->" as a prefix, so their data member names need no special marking.
> I like to distinguish protected and private data members but with a trailing underscore. I use a trailing underscore because it is less important than the data member's name. (I also use a preceding underscore for formal parameters to give them another "namespace." In that case, the underscore can't be on the end, of course.)

Thank you for your opinions on this matter.
