Step by step
Solved in 2 steps
- What would be the possible situations that a copy constructor is activated? a. It can be called to construct a new object, just like any other constructor. b. It is also called when a value parameter is an object. c. It is call when a function returns an object. d. It is call when an object is destroyed. Group of answer choices a, b, and c a, b, c, ad d b and c a only a and bCreate a class Reverse with one data member called num of type int and a static method find to return reverse of num. Create a subclass ReverseR from Reverse which overrides member of its super class. Write a main() method that tests in same class ReverseR. method find()) and this override method uses recursion to find and returns reverse of dataClass student inherits from superclass Person. Which assignment is legal? a) Student s = new Person(); b) Person p = new Student(); c) Student s = new Student(); d) Person p = new Person();
- Write a Program in java to define a Student class, with member variables String name; int cms String DegreeProg Make a default constructor, Make a parameterized constructor. Overload the above Constructor. Provide getters and setters for data members. Inside main, create 2 students objects. Take data from user and set the values for the 2 students. At the end Print daTa.When the inheritance is private, the private methods in base class are __________ in the derived class (in C++).a. Inaccessibleb.. Accessiblec.. Protectedd. PublicA car has an engine, at most 2 ACs, a handle to control the gears and a brake. If the car is manual, it has a clutch, otherwise it does not. Make three constructors of each class; a default and two parameterized. Using constructor initializer list, call the overloaded constructors of the composed and aggregated classes from the container class kindly write code in C++....
- Please answer number 1 with the subparts as they are linked altogether. 1. Create a class Vehicle.a. The class should have two fields:i. no_of_seats and no_of_wheels.b. Create two objectsi. Motorcycle and Car for this class.c. Your output should show the descriptions for Car and MotorcycleC++ 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.The base class Pet has attributes name and age. The derived class Dog inherits attributes from the base class Pet class and includes a breed attribute. Complete the program to: Create a generic pet, and print the pet's information using print_info(). Create a Dog pet, use print_info() to print the dog's information, and add a statement to print the dog's breed attribute. Ex: If the input is: Dobby 2 Kreacher 3 German Schnauzer the output is: Pet Information: Name: Dobby Age: 2 Pet Information: Name: Kreacher Age: 3 Breed: German Schnauzer code to be used: python class Pet: def __init__(self): self.name = '' self.age = 0 def print_info(self): print('Pet Information:') print(' Name:', self.name) print(' Age:', self.age) class Dog(Pet): def __init__(self): Pet.__init__(self) self.breed = '' my_pet = Pet()my_dog = Dog() pet_name = input()pet_age = int(input())dog_name = input()dog_age =…

(It is not a half-finished project.) A) This is correct. B) The answer is False.If a class X has a destructor which performs a non-trivial task (e.g., free store deallocation, freeing file handles and locks, etc.), then ____. Select one: a. the class is not likely to need constructor definitions. b. the class is likely to not need definitions for default, copy, and move constructors and copy and move assignment operators. c. the class is not likely to need constructor and assignment operator definitions. d. the class is likely to need definitions for default, copy, and move constructors and copy and move assignment operators.
