the difference between standard c and standard c++ about their underlay realization mechanism

What is the difference between standard c and standard c++ about their
underlay realization mechanism?
I think it's hard to tell all the difference in detail,just me
some your opinion.
Thanks!

The standards are available quite inexpensively from www.ansi.org in
PDF format. As for the realization mechanism, neither language
specifies one. They define an abstract machine that executes C and
C++ programs, and what the results of the execution of correct
programs on correct data should be. The actual implementation, that
is the compiler, operating system, computer, and so on, are free to
use any methods at all so long as they provide the correct results.

As for the differences between C and C++, at least before the updated
1999 C standard, one of the persons most qualified to state them would
be Bjarne Stroustrup, who created C++ from C.

Start on his web page here:

Several of the links lead to discussions of the differences between
the two languages.
