Given the following Date class public class Date { private int year; private int month; private int day; public Date() { /** Implementation not shown */ } public Date(int year, int month, int day) { /** Implementation not shown */ } public void print() { /** Implementation not shown */ } } assuming that months in the Date class are numbered starting at 1, which of the following code segments will create a Date object for the date September 20, 2020 using the correct constructor Date d = new Date(); Date d = new Date(9,20); Date d = new Date(9,20,2020); Date d = new Date(2020,9,20); Date d = new Date(2020,20,9);

Which of the statements are true about the class Magazine? 01: class Magazine { 02: public: 03: Magazine (int maxSize = 100); 04: void add (Article a); 05: int numArticles() const; 06: Article getArticle (int i); 07: private: 08: Article* array; 09: int numberOfArticles; 10: }; The compiler will provide a destructor for this class. It has a default constructor It is const-correct. It has a copy constructor The programmer should provide an assignment operator

2. The MyInteger Class Problem Description: Design a class named MyInteger. The class contains: n [] [] A private int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int value. A get method that returns the int value. Methods isEven () and isOdd () that return true if the value is even or odd respectively. Static methods isEven (int) and isOdd (int) that return true if the specified value is even or odd respectively. Static methods isEven (MyInteger) and isOdd (MyInteger) that return true if the specified value is even or odd respectively. Methods equals (int) and equals (MyInteger) that return true if the value in the object is equal to the specified value. Implement the class. Write a client program that tests all methods in the class.

Given the following class definition: class employee{public: employee(); employee(string, int, double); employee(int, double); employee(string); void setData(string, int, double); void print() const; void updatePay(double); int getNumOfServiceYears() const; double getPay() const;private: string name; int numOfServiceYears; double pay;}; Create a class parttime derived from the above class that includes private members payRate and hoursWorked of type double along with a constructor and the definition of a print function that prints out all information from the base and derived class. Provide a test program that would demonstrate the working parttime class. Note: You can assume all code is stored in a single file.
