扫雷

用C语言写了一个简单的扫雷项目。实现了一下几个功能

（1）布置雷

（2）排雷（如果当前坐标不不是雷雷，当前坐标的周围也没雷雷，就会向外扩展搜索。）

（3）踩雷，炸死（第一次踩雷不被炸死）

（4）排雷成功判断

实现原理：

雷的信息存储和排查出来的信息存储，用二维数组来存储

为了了实现⼀一个 9*9 的雷雷阵，我们需要创建⼀一个 11*11的数组 。（为了了⽅方便便统计雷雷区边上坐标周围雷的个数）

实现关键步骤：

（1）布置雷

利用rand函数生成随机坐标进行布雷

（2）扫雷

第一次不被炸死

遇到雷炸死

不是雷统计周围雷的个数，如果周围雷的个数为0就进行展开

（3)循环扫雷，直到所有的雷被排出来，就排雷成功

测试函数
