Variable Naming Conventions in C++
What's to dislike or mock about "ppMyObjects" in this example apart from it being somewhat ugly? I don't have strong opinions either way, but it does communicate useful information at a glance that "MyObjects" does not.
The most important thing is to be consistent. If you're working with a legacy code base, name your variables and functions consistently with the naming convention of the legacy code. If you're writing new code that is only interfacing with old code, use your naming convention in the new code, but be consistent with yourself too.
No. The "wrong hungarian notation" - especially the pp for double indirection - made some sense for early C compilers where you could write
int * i = 17;
int j = ***i;
without even a warning from the compiler (and that might even be valid code on the right hardware...).
The "true hungarian notation" (as linked by head Geek) is IMO still a valid option, but not necessarily preferred. A modern C++ application usually has dozens or hundreds of types, for which you won't find suitable prefixes.
I still use it locally in a few cases where I have to mix e.g. integer and float variables that have very similar or even identical names in the problem domain, e.g.
float fXmin, fXmax, fXpeak; // x values of range and where y=max
int iXmin, iXMax, iXpeak; // respective indices in x axis vector
However, when maintaining legacy code that does follow some conventions consistently (even if loosely), you should stick to the conventions used there - at least in the existing modules / compilation units to be maintained.
My reasoning: The purpose of coding standards is to comply with the principle of least surprise. Using one style consistently is more important than which style you use.
That kind of Hungarian Notation is fairly useless, and possibly worse than useless if you have to change the type of something. (The proper kind of Hungarian Notation is a different story.)
I suggest you use whatever your group does. If you're the only person working on the program, name them whatever way makes the most sense to you.
