 I'm about to embark on a rather large development effort, along
4 other developers.  All of us know C well (I teach it off-hours),
and we are interested in using either C++ or Objective-C.

 I've read "Object-oriented Programming:  An Evolutionary Approach"
by Brad Cox.  The book is mostly about Objective C, so I have a fairly
good handle on the capabilities of Objective C.  I know next to zip
about C++,

 I'd like to know the differences between C++ and Objective-C.
I'd also like some subjective input from someone who has worked with both
languages as to their preferences and why.

 I'm also a little confused about whether C++ is a proper superset
of C.  From Cox's book:

"C++ is particularly interesting given this book's emphasis on Objective-C,
because it contrasts what can be accomplished by redefining the programming
language itself as opposed to adding object-oriented capabilities to an
immutable base language."

This implies that C is not a subset of C++, and that C++ is a new language.
Later on in the book:

"C++ is very nearly a proper superset of C language, with a few modest
incompatibilities."

What are the few modest imcompatibilities?

Any help is greatly appreciated.  Thanx...
