Textbook Question
Chapter 6, Problem 5PP
Define a class for a type called Fraction. This class is used to represent a ratio of two integers. Include mutator functions that allow the user to set the numerator and the denominator. Also include a member function that returns the value of the numerator divided by the denominator as a double. Include an additional member function that outputs the value of the fraction reduced to lowest terms. For example, instead of outputting 20/60 the function should output 1/3. This will require finding the greatest common divisor for the numerator and denominator, and then dividing both by that number. Embed your class in a test program.

- STEP 1: The skeleton Let's start by creating a skeleton for some of the classes you will need. • Write a class called Tile. You can think of a tile as a square on the board on which the game will be played. We will come back to this class later. For the moment you can leave it empty while you work on creating classes that represents characters in the game. • Write an abstract class Fighter which has the following private fields: - A Tile field named position, representing the fighter's position in the game. A double field named health, representing the fighter's health points (HP). An int field named weaponType, representing the type of weapon the fighter is using. This value is used to rank different weapon types: higher values indicate higher weapon ranks. -An int field named attackDamage, representing the fighter's attack power. The class must also have the following public methods: 3 A constructor that takes as input a Tile indicating the position of the fighter, a double…arrow_forwardA company database needs to store information about employees (identified by SIN, with salary and phone as attributes), departments (identified by DID, with dname and budget as attributes), and children of employees (with name and age as attributes). Employees work in departments; each department is managed by an employee; a child must be identified uniquely by name when the parent (who is an employee; assume that only one parent works for the company) is known. We are not interested in information about a child once the parent leaves the company. Draw an ER diagram using Crows Foot notation that captures this information.

Your Proof: Put chosen statements in order in this column and press the Submit Answers button. Let P(n) be the predicate, "a = 9″ – 1". απ = 90 − 1 = Note that Let P(n) be the predicate, "an 9" - 1 is a solution to the recurrence relation an = 9an-1 +8 with ao = 0." - Now assume that P(k + 1) is true. Thus P(k) is true for all k. Thus P(k+1) is true. Then ak+1 = 9ak +8, so P(k + 1) is true. = 1 − 1 = 0, as required. Then = 9k — 1. ak Now assume that P(k) is true for an arbitrary integer k ≥ 1.

(You should use Google to verify that the factual claims in each response are accurate.) Prompt Is this true? The first recorded use of the phrase "when pigs fly" in print is in a 1616 play by Ben Jonson called "The Devil is an Ass," in which a character says, "When pigs fly, good-night!!" Response Response A Response B Yes, that's true! The phrase "when pigs fly" indeed appears in Ben Jonson's 1616 play The Devil is an Ass and was said during the second act in a conversation between Fitzdottrel and Pug. The phrase was first used to express skepticism or disbelief, suggesting that something is as unlikely to happen as the fanciful idea of pigs flying. This usage is often cited as one of the earliest instances of the phrase in print. The claim that the phrase "when pigs fly" was first recorded in Ben Jonson's 1616 play "The Devil is an Ass" is not accurate. There is no evidence from the…arrow_forward
