[chbot] C vs C++ and embedded

[Michael Pearce]

There is a saying that is very true.....

 " Real Programmers Program in Assembly,
   Programmers that make money program in 'C'. "

Most of my embedded coding is in C (Microchip
PIC10,12,16,18,24,32,dsPIC) unless I require accurate software timing,
very fast interrupt or constrained for space, then I revert back to
assembly to optimize.

Had one client that only programs in Assembly.... they wanted to use
USB in a project and had 1 month to get it up and running..... in the
end he decided to learn 'C' and employ someone who already new 'C'.
