直线的生成是用计算机生成图形最基本的技能，通过本实验使学生掌握如何用计算机生成直线。熟悉开发环境,生成直线。

熟悉Turbo C开发环境

分别用DDA算法、Bresenham算法生成直线-Line with computer-generated graphics to generate the most basic skills, through this experiment so that students learn how to use computer-generated lines. Familiar development environment to generate a straight line. Turbo C development environment were familiar with the DDA algorithm, Bresenham algorithm to generate a straight line
