Given the following definitions: public abstract class Manager extends Employee {...} public class Executive extends Manager { ... } What, if anything, is wrong with the following code? public class hrSystem { } public void payRaise () { } Manager m = new Manager(); O Compiler error because there is no Manager constructor. Compiler error because Manager is abstract so an instance cannot be created. No problem. The code will compile without any errors.

Create the inheritance hierarchy displayed below. The Student class has name(string) as a private data member. The Undergraduate Student class has private data member rank(string) that can be either freshman, sophmore, junior or senior. The GraduateStudent has private data member project (string). Include constrcutor and get/set functions as well as a print function in all classes. Test the class hierarchy by demonstrating polymorphic behiavior by decalring a vector containing Student, UndergraduatStudent, and GraduateStudent. Process the vector elements by calling the print function on each object in the array. Student Undergraduate Student Graduate Student

Create a base class Shape with a member function area() that returns 0. Derive two classes Circle and Triangle from the base class. Override the area() function in each derived class to calculate the area of the respective shape. Instantiate objects of both Circle and Triangle classes, and demonstrate the usage of the overridden area() functions. Expand the Shape hierarchy by adding a new class Square. Override the area() function in the Square class to calculate the area of a square. Create a function named calculateTotalArea() that takes an array of pointers to Shape objects and calculates the total area of all shapes using polymorphism.
