我已经在C中使用AI实现了m,n,k游戏。游戏运行正常,但是当我必须释放决策树时,它总是抛出一个"访问违规读取位置"例外。
这是决策树结构的实现:
typedef struct decision_tree_s {
unsigned short **board;
status_t status;
struct decision_tree_s *brother;
struct decision_tree_s *children;
} decision_tree_t;
这是delete_tree
函数的实现:
void delete_tree(decision_tree_t **tree) {
decision_tree_t *tmp;
if (*tree != NULL) {
delete_tree((*tree)->children);
delete_tree((*tree)->brother);
free(*tree);
*tree = NULL;
}
}
答案 0 :(得分:0)
你正在摧毁children
成员的两倍:第一次在for
循环中,第二次在循环之后。
您可能想要编写for循环:
for (tmp = tree->brother; tmp != NULL; tmp = tmp->brother) {
delete_tree(tmp);
}
