I have been caught out with the command GCC not recognizing C++ and
treating the file as C.  This generally leads my programs to spew up a
load of linking problems.  By using G++ you say "Hey look compiler, its
C++", even though g++ is part of the GCC suite itself.


the info page for GCC says

"
  G++ is a _compiler_, not merely a preprocessor.  G++ builds object
code directly from your C++ program source.  There is no intermediate C
version of the program.  (By contrast, for example, some other
implementations use a program that generates a C program from your C++
source.)  Avoiding an intermediate C representation of the program means
that you get better object code, and better debugging information.  The
GNU debugger, GDB, works with this information in the object code to
give you comprehensive C++ source-level editing capabilities (*note C
and C++: (gdb.info)C.).
