循环结构之FOR语句
本示例的FOR循环创建一个Mandelbrot图像。
using System;namespace a{ class Program { public static void Main(string[] args) { double realCoord,imagCoord; double realTemp,imagTemp,realTemp2,arg; int iterations; for (imagCoord=1.2;imagCoord>=-1.2;imagCoord-=0.05) { for(realCoord=-0.6;realCoord<=1.77;realCoord+=0.03) { iterations=0; realTemp=realCoord; imagTemp=imagCoord; arg=(realCoord*realCoord)+(imagCoord*imagCoord); while((arg<4)&&(iterations<40)) { realTemp2=(realTemp*realTemp)-(imagTemp*imagTemp)-realCoord; imagTemp=(2*realTemp*imagTemp)-imagCoord; realTemp=realTemp2; arg=(realTemp*realTemp)+(imagTemp*imagTemp); iterations+=1; } switch (iterations % 4) { case 0: Console.Write("."); break; case 1: Console.Write("o"); break; case 2: Console.Write("0"); break; case 3: Console.Write("@"); break; } } Console.Write("\n"); } Console.ReadKey(); } }}
