Can you implement the Derived Class Parameterized constructor? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Implement the constructor Dell(String name) of the Derived Class Dell which takes a string, name. We have already implemented the Base Class Laptop with the member function getName() and a parameterized constructor. Input# Laptop name is being passed through the parameterized constructor. Output# getName() method is returing Laptop name. Sample Input# Dell dell = new Dell("Dell Inspiron"); Sample Output# "Dell Inspiron"
Assignment Question : #include <iostream> using namespace std; class Animal { protected: int length, height; public: void set_values (int l, int h) { length = l; height = h; } virtual int cage_size (void) =0; }; A. Based on the above class definition, provide the derived classes below that will override the function cage_size from the base class Animal: i.Elephant, cage_size = 1.5 x length x height ii.Giraffe, cage_size = 2.5 x length x height B. Write the complete main () function that will create the object Elephant and Giraffe. Insert their length and height to calculate their cage_size. Note: A virtual function is a member function which is declared within a base class and is expected to be re-defined (overridden) by a derived class.

Example Code Ch 09-6Assume that Student, Employee and Retired are all extended classes of Person, and all fourclasses have different implementations of the method getMoney. Consider the following code where... indicates the required parameters for the constructors:Person p = new Person(...);int m1 = p.getMoney(); // assignment 1p = new Student(...);int m2 = p.getMoney(); // assignment 2if (m2 < 100000)p = new Employee(...);else if (m1 > 50000)p = new Retired(...);int m3 = p.getMoney(); // assignment 323. Refer to Example Code Ch 09-6: The reference to getMoney() in assignment 1 is to the classa. Personb. Studentc. Employeed. Retirede. This cannot be determined by examining the code
C++ is a programming language that can be used to Make a program that calculates the volume of different containers. Cylinder will be the base class, and its derived classes, also known as child classes or sub-classes, will be constructed. Create a parent class, Cylinder, first. Make a constant for pi, as you'll need it for any containers that aren't square. For the members, use protected. Finally, add a public function to control the volume. V = pi * (r2) * h is the formula.
Suppose, we have two related (child) classes named Doctor and Patient. Data membersrequired by each class are given below. data members of doctors name type remarks name string full name of doctor age int age of person spec string speialization of doctor data members of patient name type remarks name string full name of person age int age of he person diag string diagnosed problem Using the information given above, create the following three classes. a. A parent class named Person containing common data members and functionality ofthe child classes; Doctor and Patientb. The class Doctor which is publicly inherited from the class Personc. The class Patient which is publicly inherited from the class Person Each class must contain at least two constructors in addition to the appropriate set() and show() functions. Functions of child classes should call appropriate functions of the parent class to perform the common functionality. All the function…
