6. (Immutable Data Class Objects) Built-in types int, float, str and tuple are immutable. Data classes can simulate immutability by designating that objects of the class should be "frozen" after they're created. Client code cannot assign values to the attributes of a frozen object. Research "frozen" data classes, then reimplement this chapter's Complex class as a "frozen" data class. Show that you cannot modify a Complex object after you create it.

module 7 : can you assign the address of an object of a derived class to a pointer to the bass class? can you assign the address of an object of a base class to a pointer of derived class?
C++ please help me answer this question I will give you a good rating Thank you! 1. True or False. Explain why? _____ A function template may use non-template types, both in the body of the function and in the parameter list. _____ A non-const object (i.e. an object instantiated without the const keyword) cannot invoke a member function of the class that is declared to be const. _____ You can use the assignment operator = to set an object to another object without overloading, no exceptions.

- Implement the class “cylinder” with member variables radius and height, whichare private of type double. Define the global constant PI=3.1415 and use it incalculating the volume of the cylinder (PI*radius*radius*height).Implement in the class cylinder the following functions:a- A default constructor with default values of one.b- One constructor with two arguments. This constructor should check that thevariable is positive and does not exceed 20, otherwise the variable will beassigned its default value of one.c- A reader for each variable.d- A writer for each variable.e- A reader and a writer for diameter.f- A member function “volume” which calculates the volume of a cylinder.g- A member function “print” which prints the radius, diameter, and height of acylinder.h- A member function display_name() which displays “cylinder”.2- Write a program which declares an array of n cylinders (use n=5). Initialize thearray values by writing a loop which asks the user to input the radius and…
Problem 1: Java programComplete the Clothing class, the class should have the following instance variables, constructor(s) and instance methods:- An instance variable of type double named price.- An instance variable of type String named type.- An instance variable of type String named size.- A default “no-arg” constructor that sets the price to 29.9, the type to “TShirt” and the size to “Medium”. - An overloaded constructor that takes three parameters and set the instance variables accordingly. - A method named increasePrice that takes no parameters and returns no value, the method increases the instance variable price by 5.- An overloaded method increasePrice that takes a double parameter xand returns no value, the method increases the instance variable price by the value of parameter x.- A method named details which takes no parameters, returns no value, the method prints the Clothing item details in the format shown in the sample output.- Your output should look exactly the same…
Rectangle Class Observe the Rectangle class in rectangle.h, and you'll see it has two member variables: length_ and width_. These member variables can be modified with the "Setter functions" SetLength and SetWidth (aka mutator functions) and can be retrieved with the "getter functions" GetLength and GetWidth (aka accessor functions). You will be implementing two member functions of the Rectangle class: Area, and Perimeter. Notice that if a function belongs to a class, when we define the function outside of the class, we indicate that it is a member function of a class using the :: operator. For example, because Area() belongs to the Rectangle class, when we define the function in rectangle.cc, it is written as: int Rectangle::Area() { ... } After implementing these two member functions, you will implement a function, LargestRectangleByArea that compares two input Rectangle objects and returns which of the two is larger, based on its area. Implement the member function Area that…
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 */…

Kindly Solve this C++ question as per the instructions. Thank you for your help! Instructions: 1- Put the class definition in Flight.h and the implementation of the constructors and functions in Flight.cpp Implement the Flight.h and Flight.cpp so that class Flight contains: 4 private instance variables: Name of data type string, which describe the three electric vehicle charger types (AC975, DL521, and AC863). Destination of data type string that shows the final destination of that flight. Hour and Minute of data type int that show the departure time. A default constructor which sets all of the numeric instance variables to zero and the String instance variables to null. A constructor with 4 parameters that sets the 4 instance variables to the corresponding values passed. Implement an accessor method for each information (Flight name, Flight destination, and Flight Time) that will return the value of the instance variable. For example, the getX() method for the instance variables…
Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…
