建立一个包含四个窗口的多任务仿真程序。第一个窗口必须显示一系列的递增数，第二个必须显示一系列的递增质数，而第三个必须显示Fibonacci数列（Fibonacci数列以数字0和1开始，后头每一个数都是其前两个数的和－即0、1、1、2、3、5、8等等）。这三个窗口应该在数字达到窗口底部时或者进行滚动，或者自行清除窗口内容。第四个窗口必须显示任意半径的圆，而程序必须在按下一个Escape键时终止。-The establishment of a window contains four multi-task simulation program. The first window must show a series of incremental number, the second must show a series of incremental prime number, and a third one must show Fibonacci sequence (Fibonacci series of numbers 0 and 1 starting the first of each number are the first two and a few- that is, 0,1,1,2,3,5,8, etc.). The three windows in the figure stood at the bottom of the window or rolling, or on its own to clear the contents of the window. The fourth window must show the arbitrary radius of the circle, and the process must be a pressing Escape key to terminate.
