Assignment number: #4
Description:In this program ,a frame will be created which contains
ten "mines".When you click a button ,it will present the
number of mines around or a message of losing the game
(if the button is a mine).You can make a right click to
sign a dengerous button as well.When all the mines have
been signed ,a message box of winning the game will jump
to the screen.And the the message of the time you used in
the game.More over,you can click the button on the bottom
to restart the game.

一般都第一个都是随便点的，
然后就开始计算了，
这处1、1、1说明有一个炸d，三个一可以确定角山是一个炸d，那就点开剩下的，
就变成这样了，有数字2就说明那里有两个炸d，确定两个炸d位置，其他与2相接的肯定不是炸d 以此类推 就会出结果了。
剩下的，你来推敲吧
电脑小游戏扫雷怎么玩打开电脑在开始菜单中点击所有程序，在游戏中找到扫雷。
打开扫雷，游戏分为初级、中级、高级和自定义四种难度等级，初级最简单，炸d也最少。
小笑脸的左边数字表示炸d数量，右边数字表示所用时间，用时越短越好。
第一步可以随便点，可以点四角，也可以在中间随便点一个，第一步全凭运气，要是第一步就碰到炸d，只能说明运气不好。不能保证四角上就没有炸d。
如果点到炸d可以直接点击笑脸复活，重新开始。重新开始以后，随便点开一个，如果不是炸d，就可以看到一些数字，有1、2、3、4等，这个数字表示在数字旁边八个方向有炸d，我们只需要考虑未打开的地方就可以了，因为打开的地方是确定没有炸d的了。
比如下图这个地方可以确定炸d的位置。
7依据这种方式来排查炸d，如果确定出炸d后可以右键点击，竖上小旗子，把所有炸d都竖上小旗子就赢了，如果竖错了，也可以右键取消。
