Sorry, no. Objective-C is indeed a preprocessor, but C++ is a C superset
and the C++ 'program' is actually a *compiler* for the language C++. It
is C++ (specifically the 'cfront' pass) that does the syntactic and semantic
analysis.

The release version of C++ does happen to use your existing C compiler
as a code-generator. However, the output from C++ is a C-language version
of the internal parse tree, ie new code, not the old code with the C++
extensions translated. I understand that the C++ compiler used internally
at Bell Labs bypasses this step.

Maybe in terms of the structures, perhaps. But in terms of what
a program in the language *looks* like, C++ is far more unified. I think
Objective-C does far more violence to the syntax of C than does C++.
