State pros and cons of Cohen-Sutherland line clipping algorithm
Advantages: It is simple to learn and apply. It is best suited for lines that are totally inside or outside. It can easily be extended for 3D line clipping. Disadvantages: Clipping is costly when done repeatedly. This only applies to rectangular clipping windows. It is incapable of handling any other shape. It can be improved by including more regions (e.g. Nichol Lee Nichol approach).
