The easiest way would be to process your latex and bib files through a sed
script to replace C++ to \C++ and define a \C++ macro with the correct
space between C and +

It is possible to redefine in TeX the letter C catcode and then test if it
is followed by two +. But it is a lot of work (TeX macros are not very
easy) and maybe it is like using a hammer to kill a fly.
