Consider the following C++ code:

#include

class IntPoint { public: int x; int y;

IntPoint(int x, int y): x(x), y(y) {}

};

class Rectangle {

IntPoint corner; // Location of the rectangle's lower-left corner

int width; // The rectangle's width

int height; // The rectangle's width public: Rectangle(IntPoint pt, int w, int h):

corner((pt.x < -100) ? -100 : (pt.x > 100 ? 100 : pt.x),

(pt.y < -100) ? -100 : (pt.y > 100 ? 100 : pt.y)),

width((w < 0) ? 0 : w), height((h < 0) ? 0 : h) {} int perimeter() {

return 2*width + 2*height;

} int area() {

return width * height;

} int get_width() {

return width;

} int get_height() {

return height;

} // Returns true if rectangle r overlaps this

// rectangle object. bool intersect(Rectangle r) {

// Details omitted

}

// Returns the length of a diagonal rounded to the nearest

// integer. int diagonal() {

// Details omitted

} // Returns the geometric center of the rectangle with

// the (x,y) coordinates rounded to the nearest integer.

IntPoint center() {

// Details omitted

} bool is_inside(IntPoint pt) {

// Details omitted

}

}; int main() {

Rectangle rect1(IntPoint(2, 3), 5, 7),

rect2(IntPoint(2, 3), 1, 3),

rect3(IntPoint(2, 3), 15, 3),

rect4(IntPoint(2, 3), 5, 3);

std::cout << rect1.get_width() << ' ';

std::cout << rect1.get_height() << ' ';

std::cout << rect2.get_width() << ' ';

std::cout << rect2.get_height() << ' ';

std::cout << rect3.get_width() << ' ';

std::cout << rect3.get_height() << ' ';

std::cout << rect4.get_width() << ' ';

std::cout << rect4.get_height() << ' ';

std::cout << rect1.get_perimeter() << ' ';

std::cout << rect1.get_area() << ' ';

std::cout << rect2.get_perimeter() << ' ';

std::cout << rect2.get_area() << ' ';

std::cout << rect3.get_perimeter() << ' ';

std::cout << rect3.get_area() << ' ';

std::cout << rect4.get_perimeter() << ' ';

std::cout << rect4.get_area() << ' ';

}

Develop a Circle class that, like the Rectangle class above, provides methods to compute perimeter and area. The Rectangle instance variables are not appropriate for circles; specically, circles do have corners, and there is no need to specify a width and height. A center point and a radius more naturally describe a circle. Build your Circleclass appropriately.
