打印矩阵并将其传递给各种函数时出现奇怪的错误

Question

我收到了这个错误

*** 检测到堆栈粉碎 ***: 已终止 堕胎 (núcleo despejado) ***检测到堆栈粉碎***：终止 Abortado (núcleo despejado)

当我从第 8 行示例中选择一个值时，例如 8A 或 8C。 但是功能 play 仍然需要，但是在打印板时，它不会像应有的那样打印第 8 行。

函数change_board 具有无限循环并覆盖板边界之外的板单元，导致未定义的行为，在您的情况下会破坏堆栈内存。

逻辑不正确。您应该测试边界情况，以便 delta_line+line 和 delta_col+col 在 count_flips_dir 中也保持在适当的范围 [0..7] 内。
