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:

Area of a rectangle = length * width Create a Class that calculates and prints out the area of a rectangle. Then write code that creates an object of this Class in which given the length and width, it calculates and prints out the area of a rectangle. Your output should look like this: Area of rectangle: 87
Carpet Calculator The Westfield Carpet Company has asked you to write an application that calculates the price of carpeting for rectangular rooms. To calculate the price, you multiply the area of the floor (width times length) by the price per square foot of carpet. For example, the area of floor that is 12 feet long and 10 feet wide is 120 square feet. To cover that floor with carpet that costs $8 per square foot would cost $960. First, you should create a class named RoomDimension that has two fields: one for the length of the room and one for the width. The RoomDimension class should have a method that returns the area of the room. (The area of the room is the room’s length multiplied by the room’s width.) Next you should create a RoomCarpet class that has a RoomDimension object as a field. It should also have a field for the cost of the carpet per square foot. The RoomCarpet class should have a method that returns the total cost of the carpet. Figure 8-20 is a UML…
(Physics: acceleration) Average acceleration is defined as the change of velocity divided by the time taken to make the change, as shown in the following formula: a = (v1 - v0) / t Here, v0 is the starting velocity in meters per second, v1 is the ending velocity in meters per second, and t is the time span in seconds. Assume v0 is 5.6, v1 is 10.5, and t is 0.5, and write the code to display the average acceleration. Class Name: Exercise01_02Extra
Class Student This class represents a single student __init__(self, id: int, fist_name: str, last_name: str, town:str): """ This creates a student object with the specified ID first and last name and home town.

Additionally it should create a variable that holds the student's energy level which will be a number between 0 and 1. The student start out with 1 (100%) energy. :param id: The student's identifiaction number :param fist_name: The student's first name :param last_name: The student's last name :param town: The student's home town """ get_id(self)->int: """ Returns the ID of the student as specified in the constructor. :return: The student's ID """ get_first_name(self) -> str: """ Returns the first name of the student. :return: The student's first name """ set_first_name(self, name:str):…
OOP1 - Objects, Classes, and Encapsulation Create a program that has the following method and corresponding usage. 1. AreaCircle - compute the area of the circle
please use c# (Rectangle Class) Create class Rectangle. The class has attributes length and width, each of which defaults to 1. It has read-only properties that calculate the Perimeter and the Area of the rectangle. It has properties for both length and width. The set accessors should verify that length and width are each floating-point numbers greater than 0.0 and less than 20.0. Write an app to test class Rectangle. explain each step well
Time This class is going to represent a 24-hour cycle clock time. That means 0:0:0 (Hour:Minute:Second) is the beginning of a day and 23:59:59 is the end of the day. This class has these data members. int sec int min int hour

Create a constructor for the Student class you created. The constructor should initialize each Student’s ID number to 9999, his or her points earned to 12, and credit hours to 3 (resulting in a grade point average of 4.0). Write a program that demonstrates that the constructor works by instantiating an object and displaying the initial values. Save the application as ShowStudent2.java.
a. Create a class named Pizza. Data fields include a String for toppings (such as “pepperoni”), an integer for diameter in inches (such as 18), and a double for the price (such as P699.00). Include methods to get and set values for each of these fields. Save the class as Pizza.java. b. Create an application named TestPizza that instantiates one Pizza object and demonstrates the use of the Pizza set and get methods. Save this application as TestPizza.java.
C++ Stars This lab exercise will practice creating objects with constructors and destructors and demonstrate when constructors and destructors are called. Star Class Create a class, Star. A Star object has two member variables: its name, and a solar radius. This class should have a constructor which takes a std::string, the name of the star, and a double, the solar radius of the star. In the constructor, the Star class should print to the terminal that the star was born. For example, if you create a Star as follows: Star my_star("Saiph", 22.2); Then the constructor should print: The star Saiph was born. In the destructor, the Star class should print to the terminal that the star was destroyed, along with the number of times the volume of the sun that that star was, formatted to two decimal places. Hint: use the following line to set the precision to 2 decimal places: std::cout << std::fixed << std::setprecision(2); For example, when my_star above has its destructor called,…
