1. Compare Bresenham line generation with Digital Differential Analyzer line generation.
Ans. Bresenham line generation algorithm is better than Digital Differential Analyzer since it has better solution to the idea of approximation of pixel position to be enlightened for the exhibit of any type of graphic primitive, hence, decreases the staircase effect.
