C++HurdleGame The HurdleGame class contains all the functions invoked as a result of a user action (i.e. when a user presses a key on the Hurdle Frontend, one of the functions in HurdleGame will be called. A HurdleGame object comprises a HurdleWords object (which stores all valid guesses and valid Hurdles), and a HurdleState object, which stores and tracks all the game states. Any action should update the HurdleState object.Each function in HurdleGame is called as a result of a user action on the Hurdle Frontend. To understand this, please read the Hurdle Backend API section below before implementing. You are responsible for implementing each of the functions below. LetterEntered ● Called by the Hurdle frontend when the user enters a letter. ● Hint: when a user enters a letter, how should the underlying HurdleState be modified to reflect the change resulting from that key press? WordSubmitted ● Called by the Hurdle front end when the user submits a guess by pressing enter. ● Hint: when…
Language: C++ Imagine that you are in the design stage of a software system for handling the data of the partici- pants of a major soccer tournament. As different roles will be present (players, coaches, referees, etc.) you are required to develop a class handling the data of a generic league member. For each person the following data is at least needed • first name as character array (36 characters characters including '\ 0') • last name as character array (36 characters) • date of birth as character array (11 characters, storage format is yyyy-mm-dd) In addition the whole team is located somewhere, so location is an additional static prop- erty of the class. Design and implement a class for holding these data. In addition add at least two other general properties to this class. The class, which will be called TournamentMember, should provide constructors (empty and parametric), a destructor and also a copy constructor. The class should also provide inline setter and getter methods…
Write the following program with C++ Create a class: Bill_Generator The Purchased_item should be having the following data members itemPrice //for per unit price itemQty //for quantity purchased itemAmount[n] // for price of each item, n represent size of the array total_amount //for the total amount of bill that is to be paid items[n] //an array of purchased_item(item names); n represent size of the array class should have the following member functions Constructor : will take a parameter to set size of items array. getIteminfo(): will take item information calcBill(): will calculate the bill for the items purchased. Give discount of 5% for the purchase greater than 3000 pkr. showBillInfo(): display the bill with items information, given below the output item price quantity Amount LUX 50 5 250 TUC 15 3 45
Write a C++ program, you will create a class called Books to hold the information about the books in a library. The information required for each book is as follows Book Title Author name Publisher Publish year Subject Book ID (identical 5 digits’ number) Implement the following getBookInfo () member function that receives a pointer to a book and fills it up with user data. User input validation is necessary. The user should be properly prompted for each field. void getBookInfo (Books *b) Implement the following printBookInfo () member function. void printBookInfo (Books *b) Your function should print the book in the following format: Book Title : Object Oriented Programming Using C++ Author : Chris M.

PLEASE CODE IN PYTHON PLEASE USE NESTED CLASS FUNCTION Design a Point Class with attributes X and Y coordinates. The Class should have following functions: a) change the coordinates, b) return a 2 element list [x,y] c) print a Point object. d) return distance from this instance to a given [x,y] Also design a Line Class which has 2 Point attributes. The Line class should have functions for following behaviours: a) Return the length of the line. b) Print the equation of the line c) Find if this instance is equal in length to another line.
Create a class of type student .Members will include: name, gpa, rank (year) Make sure all data is private and all functions are public. Write member functions to:Set or initialize the dataRetrieve the data (get’em and set’em )Announce names of students who are eligible for a scholarship (those who have a GPA of 3.0 or higher)The program will declare at least two objects (pupils) of your new class and test each of the functions (OR if you would like to try your hand at vectors, create them dynamically- this may require a little research/review on your part).

Create a class named Shape. private attributes: Point points[6] int howManyPoints; Create a Main Menu: Add a Triangle shape Add a Rectangle shape Add a Pentagon shape Add a Hexagon shape Exit All class functions should be well defined in the scope of this lab. Use operator overloading for the array in Shape class. Once you ask the points of any shape it will display in the terminal the points added.
java language A system needs to have a Validation class that can validate the input for instance variables ofthe different classes given in Table 1. It should validate the values for the data members from different classesusing Regular Expressions, such that a name can only contain alphabets from A to Z or a to z and the firstletter is always a capital letter. The address should start with a number followed by one or two words (forexample 16 Khyber or 16 Khyber Ave). The phone number should have a format like 0-000-0000000 where the first digit is always a 0. The e-mail address should contain exactly one ‘@’ character and at least one ‘.’character. A car’s registration number can only contain a maximum of 3 English alphabets followed by notmore than 4 digits. All the classes should be able to validate their data without creating the objects
The program has to be in c++ Write a receipt class that simulates the receipts received in the store in a simplified form. Class to contain as data members• The name of the store• Array of prices of purchased goods and member functions: Constructors get () and set () - for prices to work with individual elements of the array show () - displays a list of prices, the goods to be named product # 1, product # 2, etc. total () - determines the total price of the goods remove () - removes a product from the list (according to its index) discount () - reduces the price of goods by a certain percentage (the index of the goods in the array and the percentage are submitted as parameters) other member functions if desired In the main function, illustrate how to work with the methods of the receipt class.

The class definition for an Item is given in the image UML diagram below Note: getInfo() returns a string containing ALL of the state information neatly organized. Part 1: Create a class based on the specification above. Reminder: – means private and + means public. Part 2: a)Write a function/method called “addItem” that takes: An array of items The number of items in the array An integer representing a barcode A string representing the name of an item A string representing the description of an item A double value representing the price The function must create and add the item to the array if there is space. The function must return “true” if the addition was successful and “false” otherwise. b)Write a function/method called “listItems” that takes: An array of items The number of items in the array The function must return a string containing the information on each item in the array. c)Write a function called “pricelookup” that takes : An array of items The number of…
