- Mark the following statements as true or false. The member variables of a class must be of the same type. (1) The member functions of a class must be public. (2) A class can have more than one constructor. (5) A class can have more than one destructor. (5) Both constructors and destructors can have parameters. (5)using c++ : Write a class father (name) with default constructor that prints the statement” default fatherconst.”And a constructor with parameter (name) that prints the statement (“my name is “<<name)Write a class son that inherited from the class father with the default constructor that printsthe statement “son def. const” and constructor with parameter that calls the constructor withparameter of the father class and prints (“the son name is “ <<name)37Write a class daughter that inherited from father with the default constructor that prints(“daughter def. constr.”) and a constructor with parameter that prints (“dauter name is“<<name)Write the destructor for each class as follows:Father destructor prints “father dead” and son prints “son dead” and daughter prints“daughter dead”In the main function create different objects in different scopes, pass some objects to externalfunction, create array of objects, create dynamic memory allocation of object and free themusing…A c++ a program in which class A is base class for class B. While Class C is derived from class B and class D is derived from class E. Provide explicit implementation of default constructors and destructors. Write a test program which initializes each class object and shows execution order of constructor and destructor by printing appropriate messages. Note: Solve as soon as possible use OOP Concepts
- How many default constructors can a class have? a. A class cannot have a default constructor. b. only one c. as many as it needs d. one or more, but fewer than threeExamine the following code and select the correct statements (choose all possibleoptions): class Bottle {Bottle() {}Bottle(WaterBottle w) {}}class WaterBottle extends Bottle {WaterBottle() { }WaterBottle(Bottle w) { } } a) The class Bottle defines two overloaded constructors.b) The class WaterBottle defines two overloaded constructors.c) The class compiles successfully—a base class can use reference variables of its derived class as method parameters.d) Bottle and WaterBottle cause syntax errors.e) The class compiles successfully - A derived class can use reference variables of its base class as method parameters.f) A base class can’t pass reference variables of its defined class, as method parameters in constructors.Parent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…
- You cannot use the isinstance function to determine whether an object is an instance of a subclass of a class.True or False__________ is the default behavior when an object is assigned the value of another object of the same class.Design a class named Person with properties for holding a person’s name, address, and telephone number. Next, design a class named Customer, which is derived from the Person class. The Customer class should have a property for a customer number and a Boolean property indicating whether the customer wishes to be on a mailing list. Demonstrate an object of the Customer class in a simple application.
- People in School Objective: At the end of the activity, the students should be able to: Create a program that exhibits inheritance. Procedure: Write a simple information system that will store and display the complete information of a student, faculty, or employee. Create four (4) no-modifier classes named Person, Student, Faculty, and Employee. Create a public class named CollegeList. This class shall contain the main method. Refer to the UML Class Diagram for the names of the variables and methods. The (-) symbol represents private variables, while (+) represents public method. This should be the sequence of the program upon execution: Prompt the user to select among Employee, Faculty, or Student, by pressing E, F, or S. Ask the user to type the name and contact For Employee, ask the user to type the employee's monthly salary and the department where he/she belongs to (Ex. Registrar). Then, display name, contact number, salary, and For Faculty, ask the user to press Y if…Use C++ Create a class called Fruit. Add one member variables name. Add only one getter function for the name. The get function returns name. Implement a constructor that expects name value and assigns it to the member variable. This class doesn't have an empty constructor. Create a subclass of Fruit named CitrusFruit. The CitrusFruit class has two member variables weight and color. Add a constructor which expects weight and name and color.Pass name to the base constructor and set weight and color to it's member variable. Write a program that has an array of 3 Fruits, and an array of 3 CitrusFruits. Feel free to give the name , weight and color to the object as your choice. Use loops to print out the array properties to the terminal screen.Consider the following class: 1.Write its default constructor 2.Write a code to declare an object from this class using the default constructor public class Dog { String name; String color; void barking() { } void hungry() { } void sleeping() { } }
