unsigned y

Y coordinate of the point

Public Methods

XPoint()

Constructs a clean point with the coordinates (0, 0)

XPoint(unsigned __x, unsigned __y)

Constructs a new point with the coordinates (__x, __y)

void Assign(unsigned __x, unsigned __y)

Assigns the specified coordinates to the point

XPoint& operator += (XPoint __delta)

Translates the point by the coordinates of the specified point

XPoint& operator -= (XPoint __delta)

Negatively translates the point by the coordinates of the specified point

XPoint operator + (XPoint __p)

Adds the coordinates of two points and returns the result as point

XPoint operator - (XPoint __p)

Substracts the coordinates of two points and returns the result as point

XPoint& operator = (XPoint __p)

Assigns the point the coordinates of the specified point

bool operator == (XPoint __p)

Compares the coordinates of two points and returns true if they are equal

bool operator != (XPoint __p)

Compares the coordinates of two points and returns false if they are equal

bool operator < (XPoint __p)

Compares the coordinates of two points and returns true if the first one is nearer to the origin

bool operator > (XPoint __p)

Compares the coordinates of two points and returns true if the second one is nearer to the origin

bool operator <= (XPoint __p)

Compares the coordinates of two points and returns true if the first one is nearer or as far as the second one from the origin

bool operator >= (XPoint __p)

Compares the coordinates of two points and returns true if the second one is nearer or as far as the first one from the origin

unsigned x

X coordinate of the point

unsigned y

Y coordinate of the point

XPoint()

Constructs a clean point with the coordinates (0, 0)

XPoint(unsigned __x, unsigned __y)
