There is no consensus.  Some compilers use the extension to
determine whether a file is a C or C++ file (if the compiler can
compile both languages), some do not.  Some compilers accept a
variety of extensions, some are restrictive.

For C++ main (non-header) files, I have seen: .c .C .CC .c++ .cxx

For C++ header files, I have seen: .h .hxx .h++

There may be others.

Since you usually have to specify the file extension as part of the
#include directive, the header file extension is a different category
of concern from the main C++ file extension.
