Description
Consider the class Rectangle:
class Rectangle {
public:
Rectangle(double 1, double w);
double area() const;
double getLength() const;
double getWidth() const;
private:
double length;
double width;
};
(a) Derive a class Box from the class Rectangle. Provide only the interface for the class Box. The class Box has an additional private member variable height, and an additional public member function volume(). Include an accessor for the member variable height. Redefine the area() member function for the class Box. (6)
(b) Implement the member function area() for the class Box. The outside surface area of a box is 2(hW) + 2(hL) + 2(WL), where h represents the height of the box, and W and L the width and length of the box respectively. (3)
![Modify your assignment submission code to answer the following questions: 1. Create an interface StudentModel for the student model to store student data you wish to keep unchanged such as studentID and StudentEmail. Modify the existing Student class to implement StudentModel and convert it to an abstract class with the reportReport and deleteStudent as the abstract methods. 2. Consider the following two implementation options for student search for Array and ArrayList respectively. Implement a search without a for loop, you may use methods within the two data structures to optimize the code. public void searchStudent(String searchID) { int foundIndex = findStudentByID(searchID); if (foundIndex != -1) { System.out.println("Student found:"); System.out.println("Student ID: " + studentIDs[foundIndex]); System.out.println("Student Name: " + studentNames[foundIndex]); System.out.println("Student Email: " + studentEmails[foundIndex]); System.out.println("Student Course: " + studentCourses[foundIndex]); } else { System.out.println("Student with student ID " + searchID + " was not found."); } } private int findStudentByID(String searchID) { for (int i = 0; i < studentCount; i++) { if (studentIDs[i].equals(searchID)) { return i; } } return -1; }](https://gotit-pro.com/wp-content/uploads/2023/10/6391b22d-2a52-409f-a111-f25c8a39642d.png)
