cc1plus is the C++ compiler. g++ is the driver. It's the job of g++
to "drive" the whole build process. First it may call the pre-processor
(although I think that's integrated into the compiler now), then
it calls the compiler (cc1plus) to convert the pre-processed source
code into assembler, then it calls the assembler (GAS) to convert the
assembler into a machine code object file, finally it calls the linker
(LD) to combine all the object files and libraries into an executable.

So g++/gcc is the program that manages all the various stages of
compilation, cc1plus is one of those stages.
