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:
In an inheritance relationship, the __________ is the general class.
a. derived class
b. base class
c. dependent class
d. child class

- You will define three objects class Person, BookAuthor, and Book. Class Person involves a person's identity. Class BookAuthor involves a collection of books or book titles. Class Book involves the number of books in stock , book title and price. Design the three classes: The classes must use an appropriate inheritance relationship. Each class must have a constructor. Each class has at least two private data members and you must include accessors. You must test your classes by creating a BookAuthor object and printing the Person, Book and BookAuthor values from a function you create inside of BookAuthor. Make sure you use the book object correctly and put it inside of BookAuthor. in pytgiThis task helps you understand how constructors work in inheritance Create a superclass, called SuperClass. Create a constructor for it. Inside the constructor, let it print “this is super class.” Create a childclass of SuperClass, called ChildClass. Create a constructor for it. Inside the constructor, let it print “this is child class.” Create a main function and create a new object for ChildClass. Observe what’s printed in console. What will happen if you have a default constructor without parameters in addition to the one with parameters?Create class employee with properties ID, name, salary, write accessor, mutator &constructor for the class. In main create three objects of class & find the employee with the highestsalary.
- 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.Create an abstract super class called Employee with the following attributes: Use JavaDoc comments in the Parent and Child Classes only but use @author for the driver name : String and the following methods getter and setter for the one attribute two constructors an abstract method called getPay() equals() toString() Create a sub class of Employee called SalaryEmployee with the following attribute yearlyPay : double and the following methods getter and setter for the one attribute two constructors getPay() that returns the yearlyPay divided by 52 equals() toString() Create a sub class of Employee called HourlyEmployee with the following attributes: hoursWorked : double payrate : double and the following methods getters and setters for the two attributes two constructors getPay() that returns the weekly pay (multiply hoursWorked by payrate - overtime included and 1.5 times payrate for hours > 40) equals() toString() Create a sub class of Employee called SalesEmployee with the…Q2. Write a class Bank that has the following data members –Account Holder name (ah_name[]) –Account number (ac_number) •Must unique, system generates automatically, and must starting from 100 (Hints: Use another static variable and assign that variable to ac_number) –Balance in the account (ac_balance) •The class has the following member functions –A constructor to initialize the data members –Input() to takes name from the user –Deposit(parameter) to deposits balance in the account •Must accept parameter (The amount to deposit) –Withdraw(parameter) to withdraws balance after checking •Must accept parameter (The amount to withdraw) –Display() to show the name, account number, and balance
- If you are designing an application for a car dealership, you will create a Vehicle parent class and then extend the class into Car, Truck, SUV child classes. The Vehicle class will have the general attributes and behaviors. Then, you only need to code the specific differences in the child classes. Give us an example of objects that might have similar attributes and behaviors but enough differences to warrant an inheritance relationship. Then, explain the relationship and teach your classmates about inheritance.Write a class Person that has attributes of id, name and address. It has a constructor to initialize, a member function to input and a member function to display data members. Create another class Student that inherits Person class. It has additional attributes of rollnumber and marks. It also has member function to input and display its data members. Write a simple C++ code as I am a beginner.5.Which type of inheritance is illustrated by the following code? class student{ public: int marks; }; class topper: public student { public: char grade; }; class average{ public: int makrs_needed; }; class section: public average{ public: char name[10]; }; class overall: public average{ public: int students; }; i Single level ii Multilevel and single level iii Hierarchical iv Hierarchical and single level

Create classes Dog2, Cat2, Fish2, Bird2 to inherited from Animal class. Create PetOwner2 class to test the inheritance and polymorphism. please share a screen shot of the code.How many default constructors can a class have? a. A class cannot have a default constructor. b. only one c. as many as it needs d. one or more, but fewer than three
