Please i will like to know how to add new doctors to the array and remove existing ones as well as modify doctor name.
Management of doctors is not implemented in this tutorial. The doctor data is stored in the database, in a table called "doctor":
CREATE TABLE doctor (
doctor_id INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL,
doctor_name VARCHAR (100) NOT NULL
You can simply modify that table to add/remove/delete doctors.
can you provide an solution for this
