Indeed there are c++ compilers who, if used to compile c code, could

would not get different things.

I've never heard of such a thing.

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++.

 1. The file suffix is not "something /in the code/ that is not strictly C".
    The front end of a compiler collection selecting a compiler based
    on file suffix is not an example of switching language based
    on syntax in the file.
 2. g++ does not behave this way.
     In fact .C (capital C) is one of the conventions for C++ files. I
    seem to remember that the convention was used at A&T and in fact you
    can find examples of it in the source code of Cfront (the historic
    C++ to C transpiler originally developed by B. Stroustrup).
        For g++ to assume that a .C file is C and not C++ would be insanely
    poor.
        The g++ command even assumes that .c files are C++!
     Conversely, when you use the gcc driver command on a .C file,
    you get the C++ compiler!
 Since you'r posting to Usenet, you're obviously connected to the same
Internet as the rest of us, so it's amazing you're not able to check
your facts. You know about g++, so presumbly you have an installation of
it somewhere, where you could run a 30 second experiment.
 

About what you are talking about I must apologize for one thing: in my
message that you actually report '.c' is written in capital letters.
Unfortunately, Google-Translator transforms everything that look like
brands or very short texts (c, c++, g++, ...) and initially I have not
noticed this. I hope to be apologized because I write every sentence
several times to be able to find a translation as close as possible to
what I would like to write. In relation to the tests you request, I
would like to point out that in Sun-26-May-2024-19:11:31+0200 I also
posted one that, If you had seen, perhaps, it would have avoided this
post.
'.c' in GT -> '. C'
(c, c++, g++, ...) in GT -> (C, C ++, G ++, ...)
