Question

C++

Design: Create a UML Class diagram that reflects the software design of your entire program

Q3. Create a class called Passenger that represents passengers of an airline company. A passenger is defined by the following information:
- Passenger ID (int)
- Name (string)
- Address (string)
- Tel (string)
- Date of birth (of type Date from Q2)
Provide the following functions:
- A constructor that initializes the data members and provides default arguments.
- Accessor methods that return the value of the data members.
- Functions that change the address, tel., and date of birth of a passenger.
- A function that prints information about a passenger.
Test your class by dynamically creating two Passenger objects and calling on them the above functions.
