Also write records of all those doctors in another file named: “record2” who are taking salary more than INR 80,000. After writing records in both files, merge their contents in another file: “finalrecord” and read all records of “finalrecord” file and display on screen. [Attributes of doctor: doc_id, doc_name, doc_specialization, doc_salary]
