Question

Railway reservation System

→ Declare the base class Train with train number, name, Starting station, destination, departure time, arrival time, etc.

→ Define and declare the function getdata() and putdata() to get the train details and print the details.

→ Define search() function to search train detail using train number.

→ Declare the derived class passenger with ticket number, PNR name of the passenger, gender, age, address, phone number, etc.

→ Declare and define the function getdata1() to call search() function to get the train details and get the passenger's information.

→ Define the function display() to call putdata() and display passenger's details.

→ Create base class object.

→ Read the number of trains.

→ Create the derived class object.

→ Read the number of passengers.

→ Call the function getdata1() to each passenger

→ Call the display() function.
