Is that something people do? I have never seen a C++ file with a .c extension. I have seen plenty of C++ headers with .h extension, though.

  This is about C++ files with a .C extension, not a .c extension.

  I think it meant uppercase .C instead of lowercase .c as a C++ extension. Indeed it's pretty rare. That being said, there are indeed projects using lowercase .c extension for their "C++" file: gdb [1][2] [1] https://github.com/bminor/binutils-gdb/blob/3e5fac07975a310c90772e59c17955b4137cc49b/gdb/macroscope.c#L38 https://github.com/bminor/binutils-gdb/blob/3e5fac07975a310c...

    I see, thanks for clearing that up. (I have obviously also not seen the uppercase .C used before.)

    gcc does as well. The use of .c for a C++ file is probably a project that decided, decades later, to switch from C to C++ and didn't want to go through the hassle of renaming all of their source code files to reflect the language switch.
