In c++ Make the print function in the petRecord class virtual. Create a new main that creates a PetRecord pointer, then asks the user if they want a cat, dog or bird, and creates the appropriate pet type at the pointer (use the keyword new and the default constructor). Print its’ information using the print function, including the information specific to that pet type (works due to polymorphism). Finally, delete the object at the pointer. NOTE: Answer only if you know this answer otherwise I wil downvote also don't copy from other platforms Thankyou
Is that the case?Pointers or references are required for virtual functions that are dynamically bound.
Practice overriding. In a main, build an object of that class, and print out the object using System.out.println(). Notice that this simply reports the memory address of the object in question, and we’d like to do something more useful. To replace (or override) the toString (or equals) function. We build another toString function to override the other one that also prints out the make, model, and odometer reading for a vehicle object. Reuse your Car class in the last exercise. public class Car { //instance variables private int odometer; private String make; private String model; //overloading //constructors public Car(int odometer,String make, String model) { this.odometer = odometer; this.make = make; this.model = model; } public Car(String make, String model) { this.make = make; this.model = model; } public Car(String make) { this.make = make; } /* *getter & setter methods */…
Need help with implementing of this program in C# by using Interface. Task: RenameFile Create an interface IUndoable to represent actions that can be reversed. Create a class that renames a file, and make it undoable.
How should a software utilize pointers or references from the base class to invoke the same virtual function so that it may be used in different data types?

Describe how memory allocation is done to objects and also develop a C++ programfor employee class with following attributes such as Employee ID, Employee Name,Designation and Salary. Program should sort and display the list of employees inascending order of their salaries using object as a function argument. (Note:Employee ID must not be inputted by the user i.e., auto incremented.)
For C++, How would I call or use a function that is passed by pointer or a reference? How would I use these in this example below? I understand how passing by value works, but when it comes to passing by references and pointers, that is when I get confused. #include <iostream> using namespace std; // passing by reference in this function void pass_ref(int &ref); // passing by pointer in this function void pass_ptr(int* ptr);
In C++build a program to read that data with the following promptsa-) Create a class “name” with two data members: one for the first name (String) and one for the surname (String). The last name must be a pointer to char, the first name construct it as you prefer.b-) Create a grade class to store a subject name (String) and a grade (floating).c-) Create a class "student" that inherits from the class "name" and by composition can store the student's grades (consider that the maximum possible grades will be 6).d-) Create a group class to store the data of several students (consider a maximum of 10 students)e-) Develop a method that returns the average of the group of students.f-) Develop a method that returns the average of a student given his name and surname.g-) Develop a method that returns a list of students who have failed a subject (less than 6.0 points) given the name of the subject.h-) Develop a method that returns the first and last name of the student with the lowest…
Do all please. (a) Provide an example of a constructor method being overridden? (b) Describe Dynamic Binding as related to Class loading? (c) What is the role of a class loader? (d) What are two benefits of the Bytecode verification system?
Write a C++ class to represent an Employee. Each employee is given a name, an age, a NIC number, anaddress, and a salary. Furthermore: The Employee class should keep track of how many employees (objects) have been created inthe system. Your Employee class should initialize all of its fields via a constructor.  Create function prototypes to set and get an employee's zip code. Declare a print_employee() function that prints all of an employee object's details.(Whenever possible, use constant functions.)
Indicate whether or not the following is true:When it comes to dynamically bound virtual functions, only pointers and references are acceptable.
