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:

- 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.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 inialize all components and a function to display data membersWrite 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 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…Describe a benefit from allowing a new class to extend an existing class.Create a base class Shape with a member function area() that returns 0. Derive two classes Circle and Triangle from the base class. Override the area() function in each derived class to calculate the area of the respective shape. Instantiate objects of both Circle and Triangle classes, and demonstrate the usage of the overridden area() functions. Expand the Shape hierarchy by adding a new class Square. Override the area() function in the Square class to calculate the area of a square. Create a function named calculateTotalArea() that takes an array of pointers to Shape objects and calculates the total area of all shapes using polymorphism.
- T F Classes are good for creating scalable and maintainable codeCreate a base class Shape with a member function area() that returns 0. Derive two classes Circle and Triangle from the base class. Override the area() function in each derived class to calculate the area of the respective shape.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”.
- Given the following class declaration (with prototypes): class Carpet { private: double pricePerSqYd; public: Carpet(); void setPricePerYd(double p); void setDimensions(double l, double w); double getTotalPrice() const; }; Assume the class Carpet has been implemented. Assume the class Rectangle has been implemented. Rewrite the entire Carpet class declaration and add a member variable named size which is an instance of the Rectangle class.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 //…Using that code, add this features Multi-level Classes consisting of 3 classes (A, B, and C, with A as top superclass). Use polymorphism for one function, get_description(). Mark object the get_desciption() function in class C as "override final" so that polymorphism stops at class C. Multiple Classes consisting of 2 new classes (C and D as superclasses and E as subclass). Class C is the same class as in the Multi-level classes above. Make superclass D an Abstract Class by declaring a virtual function within the class equal to zero, "= 0". Hierarachical Classes consisting of 2 new classes (D as the superclass with E, F, and G as subclasses). Classes D and E are the same classes as described in the Multiple Classes above. A Friend Function declared in class F, called "get_private_f()". Create a private variable, "private_f" and give it a value for the friend function to access. Have class G use a public static variable, "object_num" which increments every time the class G is…
