//Write a Program in C to draw a line using DDA’s line drawing algorithm ...

This program implements the Digital Differential Analyzer (DDA) algorithm to draw a line between two points in a 2D space. * The DDA algorithm is a simple and efficient method to rasterize lines, ...

It is very difficult to draw a smooth straight line as the limited screen resolution. In this paper a new approach to line generation is proposed, which is based on DDA's line generation algorithm.
