Now, where they end up isn't so important for the picture sake.
现在,对于图片来说,它们在哪里终止不是那么重要。
So pictorially, it's as though there's now some other part of the blackboard here, maybe way up here where I can put anything I want that's accessible to main, that's accessible to swap, that's accessible to increment or any other function I might implement because it is, in fact, global.
绘画般地,它是在这里黑板上的其他部分,可能在这里的上面,我在哪里可以放置这些东西,使它们可以被main函数使用,可以被swap函数使用,可以被increment函数使用,或者我所实现的其它函数,因为它实际上是一个全局变量。
