No, C.
I think you have a lot of confusion about programming
languages. C and C++ are not comparable languages.
production software that compiles as C or C++, but go on ...
Indeed there are c++ compilers who, if used to compile c code,
could decide to call the c compiler to do the work, but if
something in the code is not strictly c, then the compilation
will be in c++, the size of the executable will increase
significantly and will need of an internal or external runtimer
to work. If it were the same thing you would not get different
things.
Oh? Do you know of a C++ compiler that actually behaves this way?
I've never heard of such a thing.

C and C++ are closely related, and C and C++ compilers often share
backends, but the two languages have different grammars. The gcc
command, for example, can invoke either a C or C++ compiler, but
it knows which language it's compiling based on the source file
name or command line options, before it's even seen the content.

There are programs that are valid C and valid C++ but with
different behavior. How would a compiler that behaves as you
describe cope with that?
For example g++ makes something similar: if you pass a file .C it
compile the C code but if the file (.C) contains C++ code then
compile C++.
No, it does not.
g++ compiles as C++ unless you tell it to compile as C with '-x c'
option.
You didn't read carefully or I didn't express myself well. I wrote
that the g++ compile c++ even if it is written inside a .c file.
However in doubt I preferred to try. If I pass to g++ a .c file that
contains c code, it compiles without any option, perhaps because it
reads as if it were c++ but in any case compiles it.
