绘制钻石图形的算法改进及拓展--苏教版《算法与程序设计》“用解析法解决问题”的思考

摘要

针对信息技术选修课本《算法与程序设计》第三章第一节“用解析法解决问题”中绘制“钻石图形”的实例中较为复杂的算法，提出更简洁的算法改进意见，并由此算法引申出各种不同图形如近似圆形、多边形、五角星等图形的算法，以开拓学生思维。%Contrary to the more complex algorithm to draw"Diamond graphic"example of the first section of the third chapter on the elective course of the information technology, proposed More concise algorithm improvements, and by this algorithm gives algorithms of different shapes such as round, polygon approximation, star graph algorithm to develop students' thinking.
