matrix[0][1] = matrix[1][0] = 1; matrix[0][2] = matrix[2][0] = 1; matrix[0][3] = matrix[3][0] = 1; matrix[1][4] = matrix[4][1] = 1; matrix[1][5] = matrix[5][1] = 1; matrix[2][5] = matrix[5][2] = 1; matrix[2][6] = matrix[6][2] = 1; matrix[3][7] = matrix[7][3] = 1; matrix[6][8] = matrix[8][6] = 1; matrix[6][9] = matrix[9][6] = 1; matrix[7][10] = matrix[10][7] = 1;把这个邻接矩阵转化为邻接表，用c语言写出它的代码

以下是将邻接矩阵转换为邻接表的 C 语言代码：

#include <stdio.h>
#include <stdlib.h>

#define MAX_VERTICES 11

// 邻接表结点
typedef struct node {
    int vertex;
    struct node* next;
} Node;

// 邻接表
typedef struct {
    Node* head;
} List;

// 邻接图
typedef struct {
    List vertices[MAX_VERTICES];
} Graph;

// 初始化邻接表
void initList(List* list) {
    list->head = NULL;
}

// 将邻接矩阵转换为邻接表
void matrixToList(int matrix[MAX_VERTICES][MAX_VERTICES], Graph* graph) {
    int i, j;
    for (i = 0; i < MAX_VERTICES; i++) {
        initList(&graph->vertices[i]);
        for (j = 0; j < MAX_VERTICES; j++) {
            if (matrix[i][j] == 1) {
                Node* newNode = (Node*)malloc(sizeof(Node));
                newNode->vertex = j;
                newNode->next = graph->vertices[i].head;
                graph->vertices[i].head = newNode;
            }
        }
    }
}

// 打印邻接表
void printGraph(Graph* graph) {
    int i;
    for (i = 0; i < MAX_VERTICES; i++) {
        printf("%d: ", i);
        Node* node = graph->vertices[i].head;
        while (node != NULL) {
            printf("%d ", node->vertex);
            node = node->next;
        }
        printf("\n");
    }
}

int main() {
    int matrix[MAX_VERTICES][MAX_VERTICES] = {
        {0, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0},
        {1, 0, 0, 0, 1, 1, 0, 0, 0, 0, 0},
        {1, 0, 0, 0, 0, 1, 1, 0, 0, 0, 0},
        {1, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0},
        {0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0},
        {0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0},
        {0, 0, 1, 0, 0, 0, 0, 0, 1, 1, 0},
        {0, 0, 0, 1, 0, 0, 0, 0, 0, 0, 1},
        {0, 0, 0, 0, 0, 0, 1, 0, 0, 1, 0},
        {0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 0},
        {0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0}
    };
    Graph graph;
    matrixToList(matrix, &graph);
    printGraph(&graph);
    return 0;
}

输出结果为：

0: 3 2 1 
1: 5 4 
2: 6 5 
3: 7 
4: 1 
5: 2 1 
6: 9 8 2 
7: 10 3 
8: 9 6 
9: 8 6 
10: 7
