1. Design and implement a class named "Subject" using The class should store subject name, level of the subject, credits of the subject, name of the teacher who teaches the subject. The class has three member functions:

• First to input information into all the data members of an object.

• Second to display information of an object.

• Third function takes a parameter "Subject name". It returns true, if the parameter value passed to this function is identical to the value stored in subject name data member of the object.

Write appropriate main( function that creates a list of five "Subject" objects in an array. The main( function should demonstrate all the member functions of the class.

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

Design and implement the classes in the hierarchy using 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_course_info( that prints all the data of the object of that class. You must demonstrate polymorphism using print_course_info( and main( functions.
