Create a class “patient” with data members Patient_id and Oxygen_level.

    Create another class “covid” with character data member “test” (this can take value either ’p’ or ‘n’). Data members of both the classes should be initialized using constructor.

Class “oxygen_supply” is inherited from both the above classes. Include member function eligibility_supply which checks whether a patient needs oxygen supply or not.

If the patient has tested to positive(‘p’) and Oxygen_level is below 90, then print “patient needs oxygen supply”.

If the patient has tested to negative(‘n’) and Oxygen_level is below 90, then print “patient needs oxygen supply”.
