I post all I have done.
There are still some undetected bugs, but it works on and decent *niix

The C++ code is attached at the end.
To use all of this, I run the command
lyx -e latex PC.lyx && LyX2LaTeX2highlight2LaTeX PC.tex && latex
PC.tex && latex PC.tex && dvips -o PC.ps PC.dvi
Be aware of the fact that sometimes LyX does ugly things!! Real ugly things.
It cut's of lines in my code.
For example
cout<<a<<endl<<b<<endl<<c<<endl<<d;
might be cut into two lines, and then all is lost.
WHY is LyX doing this to me??? I don't get it, perhaps some LyX guru knows.
Please respond with improvements.
Here is the C++ code that I use for the LyX2LaTeX2hightlight2LaTeX program
It's ugly, but it works. There are still a few bugs (undetected c++ code that
doesn't transforms into something nice), like
#include transforms into \#include, but I'll fix that soon.
