当在C中使用2d阵列操作游戏时，它会进入不正确的方向

Question

我正在创建一个十五岁的游戏，但由于我在移动方法中迭代这两个if语句使其上升而不是上下移动，因此它无法工作。由于这个原因，我无法继续进行，并进一步增加了程序的复杂性。对不起，如果问题最终变得容易，我是新手编码，我正在努力改进，但有些小事情在这里和那里抓住我。谢谢你的时间，这里是代码:(虽然问题在于Move（）方法（IMO））

/**
 * fifteen.c
 *
 * Implements Game of Fifteen (generalized to d x d).
 *
 * Usage: fifteen d
 *
 * whereby the board's dimensions are to be d x d,
 * where d must be in [DIM_MIN,DIM_MAX]
 *
 * Note that usleep is obsolete, but it offers more granularity than
 * sleep and is simpler to use than nanosleep; `man usleep` for more.
