Question

The Rectangle class has been declared and main makes use of it. Add the function implementations so the code compiles and runs successfully.

Hint: Every function name is going to need Rectangle:: in front of its name.

Code:

#include <iostream>

using namespace std;

class Rectangle {

public:

Rectangle(double theWidth, double theHeight);

double getWidth();

double getHeight();

double getPerimeter();

double getArea();

void scale(double scaleFactor);

private:

double width;

double height;

};

//Do not modify anything on or above the line below this

//YOUR_CODE_BELOW

//YOUR_CODE

//YOUR_CODE_ABOVE

//Do not modify anything on or below the line above this

int main()

{

//create a rectangle with a width of 10 and a height of 20

Rectangle r1(10, 20);

cout << r1.getWidth() << " " << r1.getHeight() << endl;

cout << r1.getPerimeter() << endl;

cout << r1.getArea() << endl;

//reduce the rectangle to half its former size

r1.scale(0.5);

cout << r1.getWidth() << " " << r1.getHeight() << endl;

cout << r1.getPerimeter() << endl;

cout << r1.getArea() << endl;

}

//YOUR_CODE

Rectangle::Rectangle(double theWidth, double theHeight)

{

this->width = theWidth;

this->height = theHeight;

}

double Rectangle::getWidth() { return(width); }

double Rectangle::getHeight() { return(height); }

double Rectangle::getPerimeter() { return (2*height+2*width); }

double Rectangle::getArea() { return(height*width); }

void Rectangle::scale(double scaleFactor)

{

if (scaleFactor>0)

{

width *= scaleFactor; height*=scaleFactor;

}

else

{

//need to set an error flag here or return some negative value

}
