1. Design and implement a class named "Engineer" using C . The class should store Engineer name, branch of engineering, year of passing, present salary and organisation working on. The class has the following two member functions:

• First function for input of values to all the data members of an object

• Second function takes a parameter branch of Engineering and returns true if parameter value and stored value in the object matches

Write appropriate main( function that creates an array of three objects. The main( should demonstrate all the functionalities of the class. The data input should be meaningful.

2. Consider the following class hierarchy along with suggested data members: <img src='./qimages/12515-2.jpg'>

Design and implement the classes in the hierarchy using C . You may add more data members, if needed. You should include at least one constructor in each class. All the classes should have a member function print-patient_info( that prints all the data stored in the object of that class. You must demonstrate polymorphism using the print_patient_info( and main( functions.
