1. Design and implement a class using The class should store the name, qualification, experience and salary of machine room operators (MRO). The class should have the following two member functions:

A function that inputs data in the data members of an object.

A function that displays all the information stored in an object.

Write appropriate main( function that uses an array to create a list of three "MRO" objects. The main( function should demonstrate all the functions of MRO class. You must store meaningful values in the objects.

2. Consider the following class hierarchy along with suggested data members:

Mobiles • Make
• Year of manufacture
Smart Non-smart
• Memory • Size of address book
• Processor

Design and implement the classes in given hierarchy using You may add more data members in the classes, if needed. You should include at least one constructor in each class. All the classes should have one member function "print_mobile_info( which should display all the data of that object. You must demonstrate polymorphism using "print_mobile_info()" and "main()" function
