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:

If every C1 class object can be used as a C2 class object, the relationship between the two classes should be implemented using _________.
Step by step
Solved in 2 steps
- A class Student has Roll No, Branch, class Internal_exam has sub1marks, sub2 marks, class External_exam has sub1marks and class Result has Total as data members. Write necessary member functions to input and print data. (i) Calculate Internal_exam and External_exam subtotals using their respective member functions.(ii) Class Result has a function to calculate Total=internal+ external subtotals. Write a complete program to implement the hierarchy of the classes using virtual base class.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…(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
- (Protected vs. Private Base Classes) Some programmers prefer not to use protected accessbecause they believe it breaks the encapsulation of the base class. Discuss the relative merits of usingprotected access vs. using private access in base classes.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 //…Write a class named as vehicle which has some attributes this class has three functions.i.e.fuelAmount ()loadingCapacity()applyBrakes()enginePower()Write a class named as Bus, Car and Truck which are inherited from class Vehicle. Also write the setter/getter, default and parameterized constructor in each class. Write a main which create object of derived class and call all inherited function of base class.Note: Each class should have at least two attribute of base class.
- 7. PersonData and CustomerData classesDesign a class named PersonData with the following member variables:lastNamefirstNameaddresscitystatezipphoneWrite 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:customerNumbermailingListThe 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. Demonstrate an object of the CustomerData class in a simple program.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.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.
- plz write in java language i urgently need it Write a base class Computer that contains data members of wordsize(in bits), memorysize (in megabytes), storagesize (in megabytes) and speed (in megahertz). Derive a Laptop class that is a 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 initialize all components and a function to display data members(Rational Class) Create a class called Rational for performing arithmetic with fractions.Write a program to test your class. Use integer variables to represent the private data of the class—the numerator and the denominator. Provide a constructor that enables an object of this class to beinitialized when it’s declared. The constructor should contain default values in case no initializersare provided and should store the fraction in reduced form. For example, the fractionwould be stored in the object as 1 in the numerator and 2 in the denominator. Provide publicmember functions that perform each of the following tasks:a) Adding two Rational numbers. The result should be stored in reduced form.b) Subtracting two Rational numbers. The result should be stored in reduced form.c) Multiplying two Rational numbers. The result should be stored in reduced form.d) Dividing two Rational numbers. The result should be stored in reduced form.e) Printing Rational numbers in the form a/b, where a is…PLZ help wiith the following: IN JAVA If an inner class contains non static members, then the class name must be modified by the keyword: Final Static Void Protected
