Yup :-)

Maybe.  This is entirely dependent on your compiler and system.  Some
make it trivial, some make it impossible, and I'm sure there are many
variations in between.

Most UNIX environments with FORTRAN (an environment without C can
hardly be called UNIX) provide some way to interface between C an
FORTRAN.  Check your FORTRAN manual; that's usually the place to find
such information.
