上面我们已经对程序进行了扩充，实现了人对机游戏。



上面我们学习了程序扩充的思想过程，得到一些调试的经验。



但我们的收获不仅如此，如果你运行了程序，你就会发现：我们原来的保存功能还可以用。



这并不是程序扩充的偶然。



或许你并不感到惊喜，那么，我将告诉你的是：在后面我们将对这个程序进行再一次的扩展（联机游戏），它将不再适应了。



而这却是程序扩充的必然

-above we have the right procedures to expand and achieve the right person for the game. We studied the above procedures to expand the thinking process, get some debugging experience. However, we not only the harvest, if you run the program, you will find : the preservation of our original function can be used. This is not a process to expand coincidence. Perhaps you do not feel delighted, then I will tell you is : We will be back in the process of expanding again (online games), it will no longer used to it. And this is the inevitable expansion process
