Chapter 11.2, Problem 18STE

Following is the definition for a class called Percent. Objects of type Percent represent percentages such as 10% or 99%. Give the definitions of the overloaded operators >> and << so that they can be used for input and output with objects of the class Percent. Assume that input always consists of an integer followed by the character ‘%’, such as 25%. All percentages are whole numbers and are stored in the int member variable named value. You do not need to define the other overloaded operators and do not need to define the constructor. You only have to define the overloaded operators >> and <<.

#include <iostream>

using namespace std;

class Percent

{

public:

friend bool operator ==(const Percent& first, const Percent& second);

friend bool operator <(const Percent& first, const Percent& second);

Percent();

Percent(int percentValue);

friend istream& operator >>(istream& ins, Percent& theObject);

//Overloads the >> operator to input values of type

//Percent.

//Precondition: If ins is a file input stream, then ins

//has already been connected to a file.

friend ostream& operator <<(ostream& outs, const Percent& aPercent);

//Overloads the << operator for output values of type

//Percent.

//Precondition: If outs is a file output stream, then

//outs has already been connected to a file.

private:

int value;

};

(1 point) By dragging statements from the left column to the right column below, give a proof by induction of the following statement: an = = 9" - 1 is a solution to the recurrence relation an = 9an-18 with ao = : 0. The correct proof will use 8 of the statements below. Statements to choose from: Note that a₁ = 9a0 + 8. Now assume that P(n) is true for all n ≥ 0. 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. By the recurrence relation, we have ak+1 = ak+1 = = 9ak + 8 = 9(9k − 1) + 8 This simplifies to 9k+19+8 = 9k+1 − 1 Then 9k+1 − 1 = 9(9*…
Given the following request to an AI chatbot, which response is more accurate? (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…
