`class GRectangle`

This type contains real-valued x, y, width, and height fields. It is used to represent the bounding box of a graphical object.

Constructor
GRectangle() GRectangle(x, y, width, height)	Creates a `GRectangle` object with the specified components.
Methods
contains(pt) contains(x, y)	Returns `true` if the rectangle contains the given point, which may be specified either as a point or as distinct coordinates.
getHeight()	Returns the height component of the rectangle.
getWidth()	Returns the width component of the rectangle.
getX()	Returns the x component of the rectangle.
getY()	Returns the y component of the rectangle.
isEmpty()	Returns `true` if the rectangle is empty.
toString()	Converts the `GRectangle` to a string in the form `"(`x`,` y`,` width`,` height`)"`.

GRectangle();
GRectangle(double x, double y, double width, double height);

Creates a GRectangle object with the specified components. If these parameters are not supplied, the default constructor sets these fields to 0.

Usage:

GRectangle empty;
GRectangle r(x, y, width, height);

double getX() const;

Returns the x component of the rectangle.

Usage:

double x = r.getX();

double getY() const;

Returns the y component of the rectangle.

Usage:

double y = pt.getY();

double getWidth() const;

Returns the width component of the rectangle.

Usage:

double width = r.getWidth();

double getHeight() const;

Returns the height component of the rectangle.

Usage:

double height = pt.getHeight();

bool isEmpty() const;

Returns true if the rectangle is empty.

Usage:

if (r.isEmpty()) ...

bool contains(GPoint pt) const;
bool contains(double x, double y) const;

Returns true if the rectangle contains the given point, which may be specified either as a point or as distinct coordinates.

Usage:

if (r.contains(pt)) ...
if (r.contains(x, y)) ...

string toString() const;

Converts the GRectangle to a string in the form "(x, y, width, height)".

Usage:

string str = r.toString();
