Chapter 2.2, Problem 14SC
Program Plan Intro
Division operation:
- The division operator uses “/” symbol.
- The integer division is the operation that returns the integer of quotient part and discards the remainder part.
- For example: Consider the division operation for “7/3” which returns the result as “2” and it discards the remainder “1”.
Modulus operation:
- The modulus operator uses “%” symbol.
- The modulus is the operation that returns the integer of remainder part and discards the quotient part.
- For example: Consider the modulus operation for “7/3” which returns the result of remainder as “1” and it discards the quotient “2”.

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.

- A 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.

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.
