Q1.) Write a Review class that has: • These private data members: • string user: ID of the user string item: ID of the item • double paid: the price of the item that the user buys • double rating: the rating that the user gives to the item • tring review: the review content that the user gives to the item • These public member functions: A default constructor to set all instance variables to a default value • A parameterized constructor (i.e., a constructor with arguments) to set all instance variables • A method for getting/setting the instance variables. A method for printing the Review's information.

Problem Statement Design a Mother class that has the following member: • A virtual printInfo function that displays the class information which is the Class's name. Design a BabyA class that is derived from the Mother class. The BabyA class should have the following: • A printInfo function that overrides from the base class. The BabyA Design a BabyB class that is derived from the Mother class. The Babys class' print function should display only the class's name. class should have the following: • A print Info function that overrides from the base class. The BabyB class' print function should display only the class's name. Write a program that has an array of Mother pointers. The array elements should be initialized to Mother, BabyA, and Babys objects. The program should then step through the array with a loop and call each object's printInfo function. Partial Solution #include using namespace std; class Mother public: //declare a virtual function } { { { class } } void printInfo()...

Employee and ProductionWorker ClassesCreate an Employee class that has properties for the following data:Employee nameEmployee numberNext, create a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have properties to hold the following data:Shift number (an integer, such as 1, 2, or 3)Hourly pay rateThe workday is divided into two shifts: day and night. The Shift property will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2.Create an application that creates an object of the ProductionWorker class and lets the user enter data for each of the object’s properties. Retrieve the object’s properties and display their values. this.ReportViewer1.Employee(); cannot reference?

1- Write a class declaration named Circle with a private member variable named radius. Write set and get functions to access the radius variable, and a function named getArea that returns the area of the circle. The area is calculated as 3.14159 * radius * radius 2- Add a default constructor to the Circle class in question (1). The constructor should initialize the radius member to 0 3- Add an overloaded constructor to the Circle class in question (2). The constructor should accept an argument and assign its value to the radius member variable

c++ class runner with constructor and COPY CONSTRUCTOR

This type of member function may be called from a function that is a member of the same class or a derived class. static private protected O None of these

A Mutator function within a class must have access to the private data item but Accessor functions should not. True False Question 32 4 pts The private and public areas of a class can appear in any order. In other words the public declarations or private declarations can come first...it does not matter. True False

C++

When a class declares an entire class as its friend, the friendship status is reciprocal. That is, each class's member functions have access to the other's private members. True False

Select the correct option for the question shown below.

Exercise 1-Account class • Design a class named Account that contains : • A private int data field named id for the account • A private double data field named balance for the account • A privet Date data field named dateCreated that stores the date when the account was created • A no-arg constructor that creates a default account • A constructor that creates an account with the specified id and initial balance • The getters (i.e., accessors) and setters (i.e., mutators) methods for id and balance • The getter method for dateCreated • A method named withdraw that withdraws a specified amount from the account • A method named deposit that deposits a specified amount to the account

Two data members: feet(int) and inches(float) Two overloaded constructors: one that takes no argument and the other that takes two arguments. Zero argument constructor initializes data members from 0 whereas two argument constructor initializes data members from the passed arguments. Two getters and two setters corresponding to two data members. A member function named toDecimal that converts a distance to decimal, e.g., if a distance equals 2 feet and 6 inches then it would become 2.5 in decimal. A member function named toString that returns a string representation of a distance, e.g., if a distance equals 2 feet and 6 inches then the corresponding string representation should be 2’-6". by using C++

The Member class has a default constructor, a constructor with one parameter, and a constructor with three parameters. Declare the following objects: • member1 with no arguments • member2 with memberName as an argument • member3 with memberName, memberAge, and memberHeight as arguments Ex: If the input is Ina 23 4.75, then the output is: Member: Unnamed, -1, 0.00 Member: Ina, -1, 0.00 Member: Ina, 23, 4.75 1 import java.util.Scanner; +Nm+ ∞o a @ HNM +inn 2 3 public class Organization { 4 public static void main(String[] args) { 5 6 7 8 9 10 11 12 13 14 15 16 17 Organization.java Member.java Scanner scnr new Scanner(System.in); String memberName; int member Age; double memberHeight; memberName = scnr.next(); memberAge scnr.nextInt (); memberHeight = scnr.nextDouble(); /* Your code goes here */ member1.print(); member2.print(); member3.print(); =
