You can represent the address of any point on the screen as a pair of x and y coordinates. That means that any time you need to operate on a given point you need to specify both the x and the y coordinate. It would be useful to be able to treat each pixel as a unit, rather than dealing with independent x-y numbers. That is where the structures ...
