- In C++ 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 • string 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.arrow_forwardProgram SpecificationUsing python, design a class named PersonData with the following member variables: lastName firstName address city state zip phone Write the appropriate accessor and mutator functions for these member variables. Next, design a class named CustomerData , which is derived from the PersonData class. The CustomerData class should have the following member variables: customerNumber mailingList The customerNumber variable will be used to hold a unique integer for each customer. The mailingList variable should be a bool . It will be set to true if the customer wishes to be on a mailing list, or false if the customer does not wish to be on a mail-ing list. Write appropriate accessor and mutator functions for these member variables. Next write a program which demonstrates an object of the CustomerData class in a program. Your program MUST use exception handling. You can choose how to implement the exception handling. Start your program with a welcome message Make sure…arrow_forwardIn C++arrow_forward
- There are two types of data members in a class: static and non-static. Provide an example of when it might be useful to have a static data member in the actual world.arrow_forwarddo part 4 import java.util.*; // Car classclass Car{ private String name; // Variable to hold car name private String model; // Variable to hold car model // Default constructor Car(){ this.name = null; this.model = null; } // Parametrised constructor Car(String name, String model){ this.name = name; this.model = model; } // Function to get car name public String getName(){ return this.name; }} // Dealer classclass Dealer{ private Car[] arr; // Array holding car objects for a dealer private int count; // Variable to hold number of cars under a dealer // Default constructor Dealer(){ arr = new Car[50]; count=0; } // Function to add a car under a dealer public void addCar(Car obj){ this.arr[this.count] = obj; this.count++; } // Function to check if a car exists under a dealer or not public boolean contains(String name){…arrow_forwardC++ #include <iostream>using namespace std; //creating struct to hold //student name,age and letter gradestruct student{ //data members string name; int age; char grade;};int main(){ //declaring object for the struct student *k = new student; //filling it with data k->name = "Kate"; k->age=24; k->grade='B'; ///then printing student data cout<<"Name:"<<k->name<<endl; cout<<"Age:"<<k->age<<endl; cout<<"Grade:"<<k->grade<<endl; return 0;}arrow_forward
