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:
Write a class declaration section for the following specifications. Include a prototype for a constructor and a member function named showData() that can be used to display data member values.
a. A class named Time that has integer data members named secs, mins, and hours

- Write a class Circle with the following properties and place the class in a separate header file: • Data Members • Radius • Center x location • Center y location Member Functions • Set and Get functions for all data members • Area function that returns the area of the circle • Distance function that has a single parameter of another Circle and returns the distance between the two circles Three parameter constructor (radius, x, y) Write a program that includes the Circle header file, constructs two different circles and demonstrates the area and distance functions.Write a Cpp program to implement a class named microwave that contains data members as Brand, and price. Write a member function to display all the data members and other data functions to change the data members.Also, initialize the data members using the constructor.Program SpecificationUsing python, design a class named PersonData with the following member variables: lastName firstName address city state zip phone Write 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: customerNumber mailingList The 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. Next write a program which demonstrates an object of the CustomerData class in a program. Your program MUST use exception handling. You can choose how to implement the exception handling. Start your program with a welcome message Make sure…
- C- Create the sub class UsedBook that is derived from the super class Book and has the following instance variables, constructor, and functions: title ( String) isbn ( String) authors (String) publisher (String) edition ( int) published_year (int) price_new (double) // the price of the book if it is new age (int) // how old the book is in years Constructor that takes all of the above variables as input parameters. set/get functions calculate_price method // the price is calculated as price_new * (1- 0.10*age) print function that prints all information related to the old book. D- Create the Testing class that has the main method and does the following: aa- Use the constructor to create instance of NewBook class and name it as new. Call compute_price function. bb- Use the constructor to create instance of usedBook class and name it used. Call compute_price function. cc- Print the related information of new and used objects using print functions. Use this following code: class…Create the class diagram and write the pseudocode for a program that will process the following attributes: studentNumber, studentName, grade, and status (will hold "Pass" or "Fail"). Name your class as "Student" and your object as "aStudent". The attributes and functions must be declared as private and public respectively. Each attribute must have its own member function when assigning values and the values must be passed from the main program as arguments. Declare one more member function to display the values of all attributes. Class Diagram Grading Criteria Pseudocode Grading Criteria Correct class name. Correct class name. 10 All attributes were declared as private 10 All attributes were declared as private. 10 Member functions were declared as public. Correct sequence. Member functions accepted values from the main program. 10 Member functions were declared as public 10 10 10 Correct sequence. Member functions accepted values from the main program Statements are structured…Write a full class definition for a class named Counter , and containing the following members: A data member counter of type int . A constructor that takes one int argument and assigns its value to counter . A function called increment that accepts no parameters and returns no value. increment adds one to the counter data member. A function called decrement that accepts no parameters and returns no value. decrement subtracts one to the counter data member. A function called getValue that accepts no parameters. It returns the value of the instance variable counter .
- Create a class vehicle with member variable as location , length , wheels and speed . Also create base classes car , truck , motorcycle, trailer which have member function as draw. Using above create a program in c++.Rewrite the calculator program using a class called calculator. Your program will keep asking the user if they want to perform more calculations or quit and will have a function displayMenu to display the different functions e.g .(1 - addition, 2- subtraction, 3- multiplication, 4- division) Your program must have appropriate constructors and member functions to initialize, access, and manipulate the data members as well as : A member function to perform the addition and return the result A member function to perform the subtraction and return the result A member function to perform the multiplication and return the result A member function to perform the division and return the resultWrite a definition of a class named Point that might be used to store and manipulate the location of a point in the plane. You will need to declare and implement the following member functions:a. A member function set that sets the private data after an object of this class is created.b. A member function to move the point by an amount along the vertical and horizontal directions specified by the first and second arguments.c. A member function to rotate the point by 90 degrees clockwise around the origin.d. Two const inspector functions to retrieve the current coordinates of the point.Document these functions with appropriate comments. Embed your class in a test program that requests data for several points from the user, creates the points, then exercises the member functions.
- Q. Create a class called ADDITION has one integer and one float data member. Use pointer to data member to find their sum and print it from main method and also use the concept of dynamic constructor.Given this class specification: Class: Student Data members: int ID Write these function definitions: 1. An external definition of a member function that can be a const member function. 2. An external definition for a member function that should not be a const member function.Create a class Person with data members Name, Age and Address. Create another class Teacher with data members Qualification and Department. Also create another class Student with data member Program and Semester. Both classes are inherited from the class Person. Every class has at least one constructor which uses base class constructor. Create member function Show Data () in each to display the information of the class. C++
