++ programming one of the image is what the output of the code is supposed to be. please use these if possible: #include using namespace std; other stuff such as #include doesn't work on my compiler. Please help me with this program. Thanks!

Each function inside the class A(n)_ is a virtual function. Provide your thoughts by filling in the blanks.

Using JAVA Part A) Design a class Message that models an e-mail message. A message has a recipient, a sender, and a message text. Support the following methods: 1)  A constructor that takes the sender and recipient. 2)  A method append that appends a line of text to the message body A method toString that makes the message into one long string like: “From: Harry Morgan%nTo: Rudolf Reindee%n . . . “ Write a program that uses this class to make a message and print it. Part B) Design a class Mailbox that stores e-mail messages, using the Message class in part a) Implement the following methods in the Message class. public void addMessage(Message m) // Adds Message M to the Mailbox public Message getMessage(int i) // returns the ith message from the Mailbox public void removeMessage(int i) // removes the ith message from the Mailbox public int mailBoxSize () // returns the number of messages in the Mailbox Write a program to demonstrate the functionality of the Mailbox. Add messages to…

Problem Class In this exercise, you are going to create the Problem class. The Problem class is used to help simulate a math fact, for example: 2 + 5 = Your class needs to contain two contructors, one that takes String, int, int that represts the operator sign(+, -, *, or /), the minimum, and maximum values for the number range, and a second constructor that takes only a String that represents the operator sign. For the second constructor, the minimum should default to zero and the maximum to ten. Your Problem object should generate 2 random integers between the minimum and maximum values (inclusively). Each Problem object should only have one set of numbers that do not change. While you may include additional helper methods, two methods need to be available to the user. The first is the answer method that should return a double that represents the answer to the problem. The second is the toString that should return a String that represents the problem. The format should be: number…

Note: It`s python coding 1. Class Implementationa) Implement a class Rectangle with two attributes, width and height.b) Implement an init method with an optional parameter type. Set the default value of the attributes of width and height to 1.c) Implement a display method to print the values of width and height.d) Instantiate two objects of type rectangle, one with arguments one without. r1 = Rectangle(4, 5) r2 = Rectangle()e) Call display() to print width and height.Example OutputWidth: 4Height: 5Width: 1Height: 1

Java-  Suppose that Vehicle is a class and Car is a new class that extends Vehicle. Write a description of which kind of assignments are permitted between Car and Vehicle variables.

class A{ int a; int b; } class B extends A{ int a; public static void main(String[] args){ B obj=new B(); } } How do you get access to the variable "a" in class A? use obj.a use obj.super.a create an object of type A and then reference the variable O both b and c

// The language is java Part I: Use of recursive method (4 points for students who need recursion/extracredit) Description: Code a class called RecursiveMultiply in which it will accept two integer arguments entered from user; pass these integers to a recursive method that returns the multiplication result of these two integers. The multiplication can be performed as repeated addition, for example, if two integers are 7 and 4: 8 * 4 = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 You will write the application with GUI and recursion to display the result in a noneditable text field, based on the user’s entry from two text fields, while an OK button is pressed. You will utilize the exception handling code as you did in your Lab 4 and Lab 5 to verify if data entered in the text fields are valid (numerical and positive data only). You will make your own decision if there is any explanation that is not described in this specification. Finally, code a driver program that will test your class…

JAVA Language   Caesar Shift  Question:  Modify the Caesar class so that it will allow various sized shifts to be used, instead of just a shift of size 3. (Hint: Use an instance variable in the Caesar class to represent the shift, add a constructor to set it, and change the encode method to use it.)         import java.util.*;     public class TestCipher {      public static void main(String[] args)  {        int shift = 7;         Caesar caesar = new Caesar();         String text = "hello world";        String encryptTxt = caesar.encrypt(text);        System.out.println(text + " encrypted with shift " + shift + " is " + encryptTxt);      }    }     abstract class Cipher {      public String encrypt(String s) {        StringBuffer result = new StringBuffer("");         // Use a StringBuffer        StringTokenizer words = new StringTokenizer(s);     // Break s into its words        while (words.hasMoreTokens()) {                     // For each word in s…
