我的项目需要帮助。该项目是关于国际象棋游戏，我必须编写代码并有一个用户可以玩游戏的界面，但这是我们的老师给我们的东西，我们只需要编码。所以我的问题是，在我的board.cpp代码和（我认为）我的所有数字中。
让我解释一下项目本身： 我有一个接口，它给我一个字符串，它包含有一个数字（或没有）的正方形和我们想要移动数字的正方形。
例如： 如果我想将 A2中的白色棋子移动到A3 ，我将收到的字符串是＆＃39; A2A3＆＃39; ，那么我必须返回char *包含一个数字（0 - 7）。所以在我运行程序之前我没有遇到任何问题，这意味着一切都很好但是当程序运行时我收到了下一条消息： check error here please
之后它指出了检查功能所在的功能（在board.cpp中），有几次我注意到了这一点：check this link please 看起来我的_wFigure（和_bFigure）没有获取intalization中的值...所以为了帮助你理解我的更多代码我粘贴在这里我的board.cpp代码：

我真的不知道为什么，但他们都在board.cpp的构建器板中获得了初始化的NULL值！
提前致谢！如果我得到了很好的解决方案，我将非常感激！
答案 0 :(得分：1)
构造函数的第一行：
Figure* _bFigure = new Figure[16];
Figure* _wFigure = new Figure[16];
实际上是创建局部变量，而不是初始化成员变量。也许你的意思是：
_bFigure = new Figure[16];
_wFigure = new Figure[16];
或者你可以完全避免使用动态数组 - 只需在标题中定义成员数组：
Figure _bFigure[16];
Figure _wFigure[16];
