Hi,
Please go through the pl/sql docs carefully before you start writing codes.
Please follow the link and read first.

declare
cursor c1 is select * from ppc_input_file;
This was wrongly written as cursor c_rec is select *from ppc_input_file;.
begin
FOR c_rec IN c1 LOOP
dbms_output.put_line('@@@@' || c_rec.device_name);
The following bold portion is unnecessary. If the count is zero the cursor for loop will not run. I am not sure of your requirement.
--IF COUNT(c_rec.ppc_method) THEN
--dbms_output.put_line('hihihh');
--ELSE
--dbms_output.put_line('nononono');
--END IF;
END LOOP;
end;
