 3   -- The Eiffel program is running first, then calls the C program which is in charge of calling the
 4   -- Eiffel feature `show_values'.
 5   -- Note that the Eiffel root object is not passed to the C world. Thus, the C code uses
 6   -- predefined `eiffel_root_object' to access the very first created Eiffel object.
