Course:  Object Oriented programming Lnaguage: C++ You have to solve the Make the program correctly and in 2 hours. kindly Make program correct as much as you can. Question: Develop a polymorphic banking program using the Account hierarchy in which two types of Accounts can be created i.e.Current Account and Saving Account respectively. Each account must have to give the interest to the bank depending upon their account type. A function of name InterestRate() will calculate the interest of account and returns the interest amount. Current Account has annual interest rate of 0.1% of actual amount and SavingAccount will have to pay interest rate of 1.0% of actual amount. Also write a main function for polymorphic calls of the functions. Note: Polymorphic calls for the functions are necessary. Necessary constructor, Destructors, setters, getters and other functions should also be defined.

(Student Inheritance Hierarchy) Draw an inheritance hierarchy for students at a universitysimilar to the hierarchy shown in Fig. 19.2. Use Student as the base class of the hierarchy, then include classes UndergraduateStudent and GraduateStudent that derive from Student. Continue toextend the hierarchy as deep (i.e., as many levels) as possible. For example, Freshman, Sophomore,Junior and Senior might derive from UndergraduateStudent, and DoctoralStudent and MastersStudent might derive from GraduateStudent. After drawing the hierarchy, discuss the relationships that exist between the classes. [Note: You do not need to write any code for this exercise.]

(Java) The Abstract Art Class Write an abstract class as follows: The class is named Art It inherits from the Comparable interface It has a private String member variable named name It has a private String member variable named artist It has a private int member variable called year It has a default constructor that assigns the values "No name" to name, "No artist" to artist and -1 to the year. This default constructor calls the three argument constructor. It has a three-argument constructor to assign values to the name, artist and year variables. It has a copy constructor that makes a copy of another non-null Art object It has getters and setters for the name, artist and year variables It has a toString() method that creates a string of artist, with name and year tabbed once on subsequent lines (see sample output) It has an equals method that compares this Art to another Object It has a compareTo method that compares in this order: 1) artist, 2) name, 3) year This class contains no…
