C#编程（3_流程控制）

标签：style blog color io ar 使用 for sp div Mandelbrot集合中的每个位置都对应于公式N=x+y*i中的一个复数。实数部分是x，虚数部分是y,i是-1的平方根。图像中的各个位置的x和y坐标对应于复数的x和y部分。图像中的每个位置用参数N来表示，它是x*x+y*y的平方根。如果这个值大于或者等于2，则这个数字对应的位置是0。如果这个参数小于2，就把N的值改为N*N-N（即N=（x*x-y*y-x）+（2*x*y-y）*i）,并再次测试这个新的N值。如果这个值大于或者等于2，则这个值对应位置是1.这个过程将一直继续下去，直到给图像中的位置赋一个值，或迭代执行的次数超过指定的次数为止。根据给图像中每个点赋予的值，在图形环境下，屏幕上会显示某种颜色的像素。但是本例使用的文本环境，所以屏幕上显示的是一个字符。 其中计算 举例： 把那个字符串赋给resultString,取决于myInterger的值与10的比较。如果myInterger的值小于10，就把第一个字符串赋给resultString；如果myInterger的值大于或者等于10，就把第二个字符串赋给resultString。这个运算符比较适用于这样简单赋值语句，但不适用于根据比较结果执行大量代码的情形。此时应该使用if语句。 C#编程（3_流程控制） 标签：style blog color io ar 使用 for sp div 原文地址：http://www.cnblogs.com/haizhibin1989/p/4051345.html
