What is Point?

C++ doesn't come with a built in Point class. So, you must define the class yourself. The following is one possible way you could go about it.

class Point {
public:
   Point();
   ~Point(int a, int b);

   int getX();
   int getY();
   void setX();
   void setY();
private:
   int x,y;
}


Point::Point(int a, int b)
{
   x = a;
   y = b;
}

int Point::getX() { return x; }

int Point::getY() { return y; }

void Point::setX(int a) { x = a; }

void Point::setY(int b) { x = b; }

C/C++ don't come with a standard point type but Windows does, it has a structure

POINT

or a class

CPoint

but you will need to have included Windows.h to get them (and be programming in a Windows environment of course).
