Slip 27 - B) Create a base class Travels with data members T_no, Company_Name.Derive a class Route with data members Route_id, Source, and Destination from Travels class. Also derive a class Reservation with data members Number_of_Seats, Travels_Class, Fare, and Travel_Date from Route. Write a C++ program to perform following necessary member functions: i, Accept details of ‘n’ reservations. ii. Display details of all reservations. iii. Display reservation details of a specified Date.
