Self-Test Exercise 17 asked you to overload the operator >> and the operator << for a class Pairs. Complete and test this exercise. Implement the default constructor and the constructors with one and two int parameters. The one-parameter constructor should initialize the first member of the pair; the second member of the pair is to be 0. Overload binary operator+ to add pairs according to the rule
(a, b) + (c, d) = (a + c, b + d)
Overload operator– analogously.
Overload operator* on Pairs and int according to the rule
(a, b) * c = (a * c, b * c)
Write a program to test all the member functions and overloaded operators in your class definition.

- "static" binding vs. "dynamic" binding: (i.e., between virtual and nonvirtual methods).arrow_forwardJAVA-Homework Write a Java program to create Human as a class with Hpersonname and Hpersonage as members of class HUman, and can make employee and Lecturer as the subclasses of Human (a class can have any number of subclasses). In the employee class, we can define grade member and in the Lecturer class also income member will be defined. 1. The program must be able to store information about employee and Lecturer. we want to store the Hpersonname and Hpersonage with grade of employee and the Hpersonname and Hpersonage with income of lecturer.arrow_forward1- Write a class that allows you to define complex numbers in C++ and call it complex. The class contains two private members named real and img. It also has a constructor to initialize its members to values other than zero. Then, write a four methods that implement the basic mathematical operations (+,-.*/) for two complex numbers. 2- The purpose of the method resize() in the IntegerArray class below is to dynamically change the size of the IntegerArray instance. This methid is implemented as follows: 1. create a new array with the desired size 2. copy the data form the old to new one 3. delete the old data 4. Make the old data pointer points to the newly created data 5. update the size field your task is to write the resize() method based on the above five steps. #include int main() { IntegerArray a(2); using namespace std; class IntegerArray { public: a.data[0] = 4; a.data[1] = 2; int *data; a.resize(5); int size; cout size = size; } -IntegerArray() { delete[] data; } void…arrow_forward
- Integrate the constructor and compute method of the doubler class. The constructor should be set to startingVal and n member variables. The compute method should double the startingVal in n times and return the result asarrow_forward- Implement the class “cylinder” with member variables radius and height, whichare private of type double. Define the global constant PI=3.1415 and use it incalculating the volume of the cylinder (PI*radius*radius*height).Implement in the class cylinder the following functions:a- A default constructor with default values of one.b- One constructor with two arguments. This constructor should check that thevariable is positive and does not exceed 20, otherwise the variable will beassigned its default value of one.c- A reader for each variable.d- A writer for each variable.e- A reader and a writer for diameter.f- A member function “volume” which calculates the volume of a cylinder.g- A member function “print” which prints the radius, diameter, and height of acylinder.h- A member function display_name() which displays “cylinder”.2- Write a program which declares an array of n cylinders (use n=5). Initialize thearray values by writing a loop which asks the user to input the radius and…arrow_forwardLocalResource(String date, String sector)- Actions of the constructor include accepting a date in the format “dd/mm/yyyy”, initializing the base class, storing the sector and storing an id as a consecutively increasing integer. Note that the constructor must ensure that the date of birth information is recorded. b. getId():Integer - returns the ID of the current instance of LocalResource c. getSector():String – returns the sector associated with the current instance of localResource d. getTRN():String – returns the trn number of the current instance of LocalResource. The process used to determine the TRN is to add the id to the number 100000000 and then returning the string equivalent. e. Update the NineToFiver class to ensure it properly extends the LocalResource class f. In method getContact() of NineToFiver, remove the comments so that the method returns "Local Employee #"+and the id of the contact. Write a concrete class LocalConsultant that extends LocalResource, and implements…arrow_forward

An address has a house number street optional apartment number city state postal code. All member variables should be private and the member functions should be public. Implement two constructors: one with an apartment number one without an appartment number. Implement a print function that prints the address with the street on one line and the city, state, and postal code on the next line. Implement a member function comesBefore that tests whether one address comes before another when the addresses are compared by postal code. Returns false if both zipcodes are equal. Use the provided main.cpp to start with. The code creates three instances of the Address class (three objects) to test your class. Each object will utilize a different constructor. You will need to add the class definition and implementation. The comesBefore function assumes one address comes before another based on zip code alone. The test will also return…arrow_forwardSUBJECT: OOPPROGRAMMING LANGUAGE: C++ ALSO ADD SCREENSHOTS OF OUTPUT. Write a class Distance to measure distance in meters and kilometers. The class should have appropriate constructors for initializing members to 0 as well as user provided values. The class should have display function to display the data members on screen. Write another class Time to measure time in hours and minutes. The class should have appropriate constructors for initializing members to 0 as well as user provided values. The class should have display function to display the data members on screen. Write another class which has appropriate functions for taking objects of the Distance class and Time class to store time and distance in a file.
