C 2D链表

Question

所以我有

struct node {
   int number;
   struct node *next;

 struct deck{
    int number;
    struct deck *next;
 };
};

我想创建一个2D链表。我怎样才能初始化这样的东西？

感谢。

Answer 1

这样的事可能吗？

struct deck{
    int number;
    struct deck *next;
}
struct node {
   int number;
   struct node *next;
   struct deck *decks;
};

struct node *current_node, *new_node;
struct deck *current_deck, *new_deck;

current_node = (struct node *) malloc (sizeof(struct node));

for (i=0; i<number_of_nodes-1;i++) {
    current_deck = (struct deck* ) malloc (sizeof(struct deck));
    current_node->decks = current_deck;
    for (j=0; j<number_of_decks_in_node_i-1; j++) {
        new_deck = (struct deck* ) malloc (sizeof(struct deck));
        current_deck->next = new_deck;
        current_deck = new_deck;
    }
    new_node = (struct node *) malloc (sizeof(struct node));
    current_node->next = new_node;
    current_node = new_node;
}

首先，您需要在节点之外的 deck 。你拥有的是有效的C ++而不是C。

你可以这样写：

struct node {
   int number;
   struct node *next;
};


struct deck{
   struct node* nodes;
   struct deck* next;
};

使用笛卡尔系统，你可以。 （顺便说一下，它还没有为我工作。试着）

struct node(){
    char data[10];
    node *x_link;
    node *y_link;
}
