- 1) Consider the following class Date, which represents a date using three ints for month, day and year: class Date { private: int month; int day; int year; public: Date() { month = day = year = 0; } Date(int m, int d, int y) { month = m; day = d; year = y; } bool operator==(Date); bool operator<(Date); }; It asks to create an implementation for both overloaded operators. == should return true if the Date objects are equivalent and false if not. < should return true if the Date of the calling object (left object) comes before the parameter Date object (right object) and false if not. Assume that all objects of class Date are valid, i.e. month is between 1 and 12, inclusive; day contains an appropriate day for the given month, and year can be anything. You don't need to demonstrate calling these operators.Use the following partial class definitions to answer the questions a-c public class A1 { public int x; private int y; protected int z; ... } public class A2 extends A1 { protected int a; private int b; ... } public class A3 extends A2 { private int q; ... } a) Which of the following is true with respect to A1, A2 and A3?

Data membersrequired by each class are given below. data members of doctors name type remarks name string full name of doctor age int age of person spec string speialization of doctor data members of patient name type remarks name string full name of person age int age of he person diag string diagnosed problem Using the information given above, create the following three classes. a. A parent class named Person containing common data members and functionality ofthe child classes; Doctor and Patientb. The class Doctor which is publicly inherited from the class Personc. The class Patient which is publicly inherited from the class Person Each class must contain at least two constructors in addition to the appropriate set() and show() functions. Functions of child classes should call appropriate functions of the parent class to perform the common functionality. All the function…Answer this in C++: In the Student.cpp file and Student.h file, build the Student class with the following specifications: Private data members string name - Initialized in default constructor to "Louie" double gpa - Initialized in default constructor to 1.0 Default constructor Public member functions SetName() - sets the student's name GetName() - returns the student's name SetGPA() - sets the student's GPA GetGPA() - returns the student's GPA Ex. If a new Student object is created, the default constructor sets name to "Louie" and gpa to 1. The output of GetName() and GetGPA() before and after calling SetName("Felix") and SetGPA(3.7) is: Louie/1 Felix/3.7 main.cpp #include <iostream> #include <vector> #include "Student.h" using namespace std; int main() { Student student = Student(); cout << student.GetName() << "/" << student.GetGPA() << endl; student.SetName("Felix"); student.SetGPA(3.7); cout <<…
- Write a class definition that creates a class called leverage with one private data member, crowbar, of type int and one public function whose declaration is void pry(). Opp JavaKindly 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…Kindly Give me (OOP) C++ codes for the following question. Question: Consider the following class definition:public class date { private int day; // from 1 to 31 private int month; // from 1 to 12 private int year; // from 2000 upwards public void advance (); // move to next day }; A) Implement a constructor that initializes new objects of date class to be set to the 1st of January 2000. B) Implement setters for day, month, and year. C) Implement the advance method, which moves to the next day, ensuring that all data members are updated appropriately.
