Calculate with pointers?

[ChocoG]

Hello, I want to create a little program... As first it should save the current Mouse position.
Then it should save it again after some seconds but this time in another pointer.
After that I want the diffrence saved in another var but this time in an int.

But _pointer - _pointer2 = diffrence; dont work.

I would be happy if you can help me
example code:

  cout << "First Position:";
	Sleep(3000);
	GetCursorPos(&_calcPlayer);
	cout << "Second Position";
	Sleep(3000);
	GetCursorPos(&_calcEnemy);
	system("CLS");
	cout << "Calculation..." << endl;
	_calcPlayer - _calcEnemy = int diffrence;

What do you mean by difference? The distance between the points? The vector to the first point relative to the second point? The other way around?

I mean the diffrence between Point 1 and point 2

What is the type of _calcPlayer and _calcEnemy?
What does the GetCursorPos() do?

One does not simply "save something in a pointer". Pointers store memory addresses. A pointer can point to an object. That object usually stores a value.


A "cursor position" (or "point") sounds like a (mathematical) 2D vector. How does one compute the "difference" of positions? Is the difference a boolean, vector, or distance? If a distance, then euclidean, manhattan, or what?
