Because both compiler drivers choose the compiler based on the
extension;
if you give them a C file, they call the C compiler.

CPP is the C preprocessor, which handles preprocessor directives
(#define
and the like) and strips comments.

Easy - with gcc/gpp -v, you're asking for the compiler driver's version,
which it reports.  With gcc -v <file>, you're asking for verbose
compilation and linking, in which case each component prints its version
information.

No - you'll need to do verbose compilation; as a rule though, all gcc
components have the same version (provided no -V, -M or -B options are
used during compilation), so the version reported by gcc -v can be used.
