我遇到了问题。我有一个象棋游戏，我想让我的棋子在船上随机移动。我不知道为什么，但当我移动一块时，下一块移动，所以我写了一个移动（第一块）。在这种情况下，只有第一件不能移动。怎么解决这个问题？

答案 0 :(得分：0)
您移动fJoc->BlackRook1[1]，但该值超出了数组BlackRook1的有效范围。
该行
bkRook1* BlackRook1[1];
只定义一个单独的元素，即BlackRook1[0]。
原因＆＃34;下一部分移动＆＃34;是纯粹的机会。 未定义的行为用于处理超出其范围的数组对象，实际上可能发生任何事情 - 包括＆＃34;似乎正常工作＆＃34;，或者，如在您的情况下，＆＃34;似乎有用，除了这个小事＃34;。
我想它恰好适合你的情况，因为所有的对象初始化都是一个接一个，所以＆＃34;超越＆＃34;愉快地指向下一个创建的。 （除了最后一个之外，就是。随意尝试。）
