`struct GPoint`

A GPoint struct contains two fields, x and y, used to specify the x,y coordinates of a point in the graphics plane.

Fields
x	Type `double`
y	Type `double`
Constructor
GPoint() GPoint(`x`, `y`)	Initializes a `GPoint` with the specified `x` and `y` coordinates.
Methods
toString()	Returns a string representation of this GPoint in the form `"(`x`,` y`)"`.

Constructor detail

GPoint();
GPoint(double x, double y);

Initializes a GPoint object with the specified x and y coordinates. If the coordinates are not supplied, the default constructor sets both fields to 0. The GPoint fields x and y also can be directly accessed using dot notation.

Usage:

GPoint origin;      // x,y = 0,0
GPoint pt(x, y);

pt.x += 10;
if (origin.y == pt.y) ...

Method detail

string toString() const;

Returns a printable string representation of this GPoint in the form "(x, y)".

Usage:

string str = pt.toString();
