in c++ write aprogram to Create a class Rectangle with length and breadth as private data members and also provide the following member functions: getdata(): gets the length and breadth of rectangle. calarea(): return the area of the rectangle. calperi(): return the perimeter of the rectangle. issquare(): return true if the rectangle is square

Goal 1: Update the Fractions Class ADD an implementation that takes an integer as a parameter. The functionality remains the same: Instead of multiplying/dividing the current object with another Fraction, it multiplies/divides with an integer. For example; a fraction 2/3 when multiplied by 4 becomes 8/3. Similarly, a fraction 2/3 when divided by 4 becomes 1/6. Goal 2: Update the Recipe Class Add a private member variable of type int to denote the serving size and initialize it to 1. Update the overloaded extraction operator (<<) to include the serving size. New Member functions to the Recipe Class: 1. Add four member functions get the value of each of the member variable of the Recipe class: getRecipeName(), getIngredientNames(), getIngredientQuantities(), getServingSize() They return the value of the respective member variables. 2. Add and implement a member function that scales the current recipe to a new serving size. The signature of this function is: void scaleRecipe(int...

C++ Create a class named Student that has three member variables:name – A string that stores the name of the studentnumClasses – An integer that tracks how many courses the student is currently enrolledinclassList – A dynamic array of strings used to store the names of the classes that thestudent is enrolled inWrite appropriate constructor(s), mutator, and accessor methods for the class along with thefollowing: A method that inputs all values from the user, including the list of class names. Thismethod will have to support input for an arbitrary number of classes. A method that outputs the name and list of all courses. A method that resets the number of classes to 0 and the classList to an empty list. An overloaded assignment operator that correctly makes a new copy of the list ofcourses. A destructor that releases all memory that has been allocated.Write a main method that tests all of your functions.

Lab Goal : This lab was designed to teach you more object oriented programming and start you down the path of creating larger programs and games like BlackJack and Elevens [ one of the new AP CS A Labs ]. You will create a Deck class that contains a List < Card >Lab Description : You need to design a class that contains an instance variables which is a List < Card > and an int that keeps track of the top card position . You then need to make a constructor and related methods. You will need a dealCard method and a shuffle method. Use the template shown below. /make a Deck classpublic static final int NUMCARDS = 52;public static String[] SUITS = "CLUBS HEARTS DIAMONDS SPADES".split(" ");private List<Card> cards;private int top;//make a Deck constructor//refer cards to new ArrayList//set top to the top of the deck 51//loop through all suits//loop through all faces 1 to 13//add a new BlackJackCard to the deck//make a dealCard() method that returns the top card//write...

Write a C#program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate. Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string) ClassRegistration -...

There are two types of data members in a class: static and non-static. Give an example of real-world use for a static data member.

In C++ Q1.) Write a Review class that has: • These private data members: • string user: ID of the user • string item: ID of the item • double paid: the price of the item that the user buys • double rating: the rating that the user gives to the item • string review: the review content that the user gives to the item • These public member functions: • A default constructor to set all instance variables to a default value • A parameterized constructor (i.e., a constructor with arguments) to set all instance variables • A method for getting/setting the instance variables. • A method for printing the Review's information.

Written in Python It should have an init method that takes two values and uses them to initialize the data members. It should have a get_age method. Docstrings for modules, functions, classes, and methods

The Spider Game Introduction: In this assignment you will be implementing a game that simulates a spider hunting for food using python. The game is played on a varying size grid board. The player controls a spider. The spider, being a fast creature, moves in the pattern that emulates a knight from the game of chess. There is also an ant that slowly moves across the board, taking steps of one square in one of the eight directions. The spider's goal is to eat the ant by entering the square it currently occupies, at which point another ant begins moving across the board from a random starting location. Game Definition: The above Figure illustrates the game. The yellow box shows the location of the spider. The green box is the current location of the ant. The blue boxes are the possible moves the spider could make. The red arrow shows the direction that the ant is moving - which, in this case, is the horizontal X-direction. When the ant is eaten, a new ant is randomly placed on one of the...
