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:
Fill-in-the-Blank
When both a base class and a derived class have constructors, the base class’s constructor is called __________ (first/last).
Step by step
Solved in 2 steps
- Write a base class Computer that contains data members of wordsize (in bits), memory size in megabytes, and storage size in megabytes and speed in megahertz. Drive a Laptop class that is kind of computer but also specifies the object’s length width, height and weight. Member functions for both classes should include a default constructor, a constructor to initializes all components and a function to display data members.Fill the gap: The________declares that a derived class is allowed to override a method.(RationalNumber Class) Create a class RationalNumber (fractions) with these capabilities:a) Create a constructor that prevents a 0 denominator in a fraction, reduces or simplifiesfractions that are not in reduced form and avoids negative denominators.b) Overload the addition, subtraction, multiplication and division operators for this class.c) Overload the relational and equality operators for this class
- M02 C++ 1. Design a class called Circle. The circle is defined by its center (x,y) and radius r. Here is the UML for the class: Circle-int x //x coord of the center-int y // y coord of the center-int radius+ Circle() //default constructor that sets origin to (0,0) and radius to 1+Circle(int x, int y, int radius) // regular constructor+getX(): int+getY(): int+getRadius(): int+setX(int newX: void+setY(int newY): void+setRadius(int newRadius):void+getArea(): double // returns the area using formula pi*r^2+getCircumference // returns the circumference using the formula 2*pi*r+toString(): String // return the circle as a string in the form (x,y) : radius2. make a specification file called CircleHeader.h which contains the class specification with member variable (attribute) declarations and function (aka instance method) headers3. make a file called Circle.cpp which implements the Circle class as given in the UML diagram above. This file will implement instance methods…#include <iostream> using namespace std; //creating an Abstract base class for the Employee class Employee { public: //declaring a pure virtual function //which get overrided in the other derived classes virtual float computeYIncome() = 0; }; //create a class ExecOfficer derived from ExecOfficer class ExecOfficer:public Employee { int salary; public: //constructor for the class ExecOfficer(int s) { salary = s; } //overriding the base class function float computeYIncome() { cout <<"The salary of Executive Officer is : "<<salary<<endl;; } }; class Worker:public Employee { int salary; public: //constructor for the class Worker(int s) { salary = s; } //overriding the base class function float computeYIncome() { cout << "The salary of Worker is : "<<salary<<endl; } }; int main() { //creating the objects of type worker and Executive Officer Worker w(12000); w.computeYIncome(); ExecOfficer E(60000); E.computeYIncome(); } main.cpp 27 19…In order to extend a class, the new class should have access to all the data and inner workings of the parent class. True False
- 1- Create a class SchoolKid that is the base class for children ar aschool . It should have attributes of the child’s name and age ,the name of the child’s teacher ,and the greeting. It should haveappropriate accessor and mutator methods for each of the attributes. Derive a class ExaggeratingKid from schoolkid , as described above . The new class should override the accessor method for the age , reporting the actual plus 2. It also should override the accessor for the greeting ,returning the child’s greeting concatenated with the words “I am the best”.C++ Exercise 2 (inheritance):Consider a circle class that has a single attribute R (radius).1. Write a program that allows you to create this class that contains:o A single attribute.o A default constructor that initializes R to 1.o A parameterized constructor.2. Create another cylinder class that inherits the circle class publicly. Theclass cylinder contains:o A single H (Height) attribute.o A parameterized constructor.o A member function to calculate and display the volume of the cylinder.(Enhanced Employee Class) Modify class Employee inFigs. 12.9–12.10 by adding a private utility function calledisValidSocialSecurityNumber . This member function shouldvalidate the format of a social security number (e.g., ###-##-#### , where # is a digit). If the format is valid, return true ;otherwise return false .
- 1.1 Class definition Define a class bankAccount to implement the basic properties of a bank account. An object of this class should store the following data: Account holder’s name (string) Account number (int) Account type (string, check/savings/business) Balance (double) Interest rate (double) – store interest rate as a decimal number. Add appropriate member functions to manipulate an object. Use a static member in the class to automatically assign account numbers. 1.2 Implement all appropriate member functions of a class. 1.3 write a program that illustrate how to use your class. Your program should have the following: Declare an array of 20 components of type bankAccount to process up to 20 customers. void menu() – helps the user to select if the customer is new or if they already exist. Furthermore, it prints the customer’s data or exits the program. Use a switch statement which uses the value from menu() as an expression to call the following user-defined functions: void…plz do it urgent in devc++. and plzz dont reject it Define a pure abstract base class called BasicShape . The BasicShape class should have the following members: Private Member Variable: area, type double used to hold the shape's area. Public Member Functions: setArea: assigns received argument to area variable. getArea. This function should return the value in the member variable area. calcArea. This function should be a pure virtual function. Next, define a class named Circle . It should be derived from the BasicShape class. It should have the following members: Private Member Variables: centerX, type integer used to hold the x coordinate of the circle’s center. centerY, type integer used to hold the y coordinate of the circle’s center. radius, type double used to hold the circle's radius. Public Member Functions: constructor—accepts values for centerX, centerY, and radius. Should also call the overridden calcArea function described below. getCenterX—returns the value in…A class is made abstract by declaring that class virtual. T/F
