C++ programming

Without knowing either lanugage, I look at the C++ version and say
"Huh?" Whereas when looking at the Java version, I at least can make
some guess as to what it does.  The example provided is exactly what
keeps me away from C++ and the like: Instead of learning a few commands
and manipulating them, one memorizes the bible, the dictionary, and the
thesaurus (or searches through some tome -- electronic or hardcopy).  
IDE's or whatever may help search the tome, but still...

Granted, the wheels that people reinvent may not be the ideal wheel, and
there'll be a lot of variations in design.  I can see where that would
be a disadvantage if you do a lot of shipping your code around to the
four corners of the universe.
