在推出井字游戏C语言版和C++版之后,作者再次推出JAVA applet版,功能更加强大,

可以用鼠标控制,点击时还有伴音!

选择菜单项可以重新玩......

C和C++版有幸加了精,希望这一款再次加精!

主要代码如下:

哈哈......

的确是demo中的例子!

不过我没说是我写的呀,你没看贴子上是[分享]和[开源]吗?

我没有用[原创]呀!

其实有很多人都不知道demo中有这个,所以让他们知道一下

代码看了,思路挺简单的,我要写也会这样写

哈哈......

不过,C和C++版的确是原创的!去看看吧!

哈哈......

嗨.我已经说的很清楚了,是demo中的一个例子,您就别这样了

反正大家学到东西就好,这是最重要的!不是吗?

再者说我也不是完全粘贴的原版,我是亲自参考那个自己做了一遍

可以说我已经可以自己编一个了.就冲这点,我觉得就应该给点奖励,

哈哈......
