And then we'll go back to our outer loop. So this is how nested loops get executed.

然后我们将回到我们的外循环。这就是嵌套循环的执行方式。

And if that message actually tells you to jump to some code, you break out of this outer while loop.

如果该消息实际上告诉您跳转到某些代码，您就会跳出这个外部 while 循环。

Then, with two loops – one nested in the other, so that the inner loop runs once for every iteration of the outer loop – we can draw a rectangle.

然后，通过两个循环——一个嵌套在另一个循环中，这样内循环在外循环的每次迭代中运行一次——我们可以绘制一个矩形。
