`class Point`

This class represents an x-y coordinate point on a two-dimensional integer grid. If you need to work with real-valued points, you should use the gtypes.h interface instead.

Constructor
Point() Point(x, y)	Creates a `Point` object with the specified x and y coordinates.
Methods
getX()	Returns the x-coordinate of the point.
getY()	Returns the y-coordinate of the point.
toString()	Returns a string representation of the `Point` in the form `"(x, y)"`.
Operators
if (p1 == p2) . . .	Returns `true` if `p1` and `p2` are the same point.
if (p1 != p2) . . .	Returns `true` if `p1` and `p2` are different
cout << pt;	Overloads the `<<` operator so that it is able to display `Point` values.

Constructor detail

Point();
Point(int x, int y);

Creates a Point object with the specified x and y coordinates. If the coordinates are not supplied, the default constructor sets these fields to 0.

Usage:

Point origin;
Point pt(x, y);

Method detail

int getX();

Returns the x-coordinate of the point.

Usage:

int x = pt.getX();

int getY();

Returns the y-coordinate of the point.

Usage:

int y = pt.getY();

string toString();

Returns a string representation of the Point in the form "(x, y)".

Usage:

string str = pt.toString();

Operator detail

bool operator==(Point p2);

Returns true if p1 and p2 are the same point.

Usage:

if (p1 == p2) . . .

bool operator!=(Point p2);

Returns true if p1 and p2 are different

Usage:

if (p1 != p2) . . .

ostream & operator<<(ostream & os, Point pt);

Overloads the << operator so that it is able to display Point values.

Usage:

cout << pt;
