OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Step by step
Solved in 2 steps
- Following the instructions presented in the Lecture 4.5 and 4.6, complete the class Bag we discussed in the lectures. It should include all the data members, constructors, as well as all the member functions we have discussed. To be more specific, the class should have an interface shown as following: class Bag { private: int items[100]; int itemCount; public: Bag(); int getItemCount(); bool add(int newItem); void display(); bool contains(); bool remove(int a); int getSum(); }; Please complete all the member functions listed above including the default constructor. Then add following member function to the class: getMax() This function returns the largest integer stored in the Bag without changing the position of each integer stored in the Bag. Write a C++ program in a .cpp file (source file) that include above class Bag and perform following tasks: Use function rand() to randomly generate 80 integers between 0 and 99 and put them into an object of the class Bag. Use…1- A complex number has the form a+bi , can be expressed as theordered pair of real numbers (a,b). The class represents the real andimaginary parts as double precision values.Provide a constructor that enables an object of this class to beinitialized when it is instantiated. The constructor should containdefault values.Provide Public member functions for each of the followingarithmetic’s functions (addition – subtraction – multiplication –division), a complex absolute value operation, printing the number inthe form (a,b), printing the real part , printing the imaginary part andfinal overload the == operator to allow comparisons of two complexnumbers.Include any additional operations that you think would be useful fora complex number class.Design, implement, and test your class.Cr3ate a class named Person, use the __init__ () function to assign values for name and age class Person: def __init__(self, name, age): _______________ _______________p1 = Person("John", 36)print(p1.name)print(p1.age)
- Write a program to computerize the billing system of a hospital. a) Design the personType class as shown below: PersonTye -firstname: String -lastname: String +print(): void +setNAme(string, string) : void +getFirstName() : string +getLastName() : string +abstract personType(): string b) Design the class doctorType, inherited from the class personType with an additional data member to store a doctor’s speciality. Add appropriate constructors and member functions to initialize, access, and manipulate the data members and this class should implement abstract method of class PersonType. c) Design the class billType with data members to store a patient’s ID and a patient’s hospital charges, such as pharmacy charges for medicine, doctor’s fee, and room charges. Add appropriate constructors and member functions to initialize and access and manipulate the data members. d) Design the class patientType, inherited…4.13 LAB: Car value (classes) Instructor note: Important Coding Guidelines: Use comments, and whitespaces around operators and assignments. Use line breaks and indent your code. Use naming conventions for variables, functions, methods, and more. This makes it easier to understand the code. Write simple code and do not over complicate the logic. Code exhibits simplicity when it’s well organized, logically minimal, and easily readable. C++ Given main(), complete the Car class (in files Car.h and Car.cpp) with member functions to set and get the purchase price of a car (SetPurchasePrice(), GetPurchasePrice()), and to output the car's information (PrintInfo()). Ex: If the input is: 2011 18000 2018 where 2011 is the car's model year, 18000 is the purchase price, and 2018 is the current year, the output is: Car's information: Model year: 2011 Purchase price: 18000 Current value: 5770 #include <iostream>#include <math.h>#include "Car.h"using namespace std; void…in c++ A complex number has the form a+bi , can be expressed as theordered pair of real numbers (a,b).

- array of Payroll ObjectsDesign a PayRoll class that has data members for an employee’shourly pay rate and number of hours worked. Write a program withan array of seven PayRoll objects. The program should read thenumber of hours each employee worked and their hourly pay ratefrom a file and call class functions to store this information in theappropriate objects. It should then call a class function, once foreach object, to return the employee’s gross pay, so this informationcan be displayed.Please read the main function and define a class CStudent. (object array, static member, string) Please do not change the main function and complete the program given. 【Description】 Please read the main function and define a class CStudent. In the main funciton, two arrays of the ojbect of CStudent are define. Please analyze the call of constructor and destructor in the process of creating and releasing objects. 1. CStudent has two private member variables:stirng name, int age. 2. CStudent has a static member count. It will be incremented by 1 when the object is created and decremented by 1 when the object is destroyed. 3. The constructor function should output "*** is contructing". The destructor function should output “*** is destructing”. "***" indicates the name of the current CStudent object. 【Input】 No input 【Output sample】 There are 0 students. noname is contructing noname is contructing noname is contructing noname is contructing noname is contructing name:noname…Write a program that has variables to store Car data like; CarModel, CarName, CarPrice and CarOwner. The program should include functions to assign user defined values to the above mentioned variable and a display function to show the values . Write a main that calls these functions Now write another runner class that declares three Car objects and displays the data of all three.
- The base class Pet has protected data members petName, and petAge. The derived class Dog extends the Pet class and includes a private data member for dogBreed. Complete main() to: create a generic pet and print information using PrintInfo(). create a Dog pet, use PrintInfo() to print information, and add a statement to print the dog's breed using the GetBreed() function. Ex. If the input is: Dobby2Kreacher3German Schnauzer the output is: Pet Information: Name: Dobby Age: 2Pet Information: Name: Kreacher Age: 3 Breed: German Schnauzer #include <iostream>#include<string>#include "Dog.h" using namespace std; int main() { string petName, dogName, dogBreed; int petAge, dogAge; Pet myPet; Dog myDog; getline(cin, petName); cin >> petAge; cin.ignore(); getline(cin, dogName); cin >> dogAge; cin.ignore(); getline(cin, dogBreed); // TODO: Create generic pet (using petName, petAge) and then call PrintInfo //…1). Develop a class named Department with two data members: name and size. The name cantake values such as "Finance", "Human Resources". size is for how many people work in thedepartment; You should provide all constructors, all get/set methods, and the toString method;2). Develop a class called Company which should have at least four data members: name,address, totalNumberOfEmployees, and departments (of type Department; an array). The relationbetween Company and Department is composition. The total number of employees is the sum ofthe sizes of all departments. You should provide all constructors, especially the constructor thatreceives departments as an initial value, all get/set methods, and the toString method;3). Create three departments: "Finance", "Human Resources", "IT". Test all constructors, andget/set methods, toString method; take screenshots;4). Create a company object with the above departments: "Finance", "Human Resources", "IT".Test all constructors, and get/set…c++ Create a class Circle having member variables Radius of type float. Make default and parametrized constructors in addition with setter methods of member variables. Make a function getArea() to return the Area of a Circle object. Overload the ‘+’ operator to add two objects of class Circle. In main(), create two objects of the class and assign them values by using setter methods. Make another object and initialize it with the sum of other two objects. Finally, display their Area
