写出从图的邻接表表示转换成邻接矩阵表示的算法， C语言写成过程形式。

以下是将图的邻接表表示转换为邻接矩阵表示的算法，使用C语言编写成过程形式：

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

#define MAX_VERTICES 100

struct Node {
    int vertex;
    struct Node* next;
};

struct Graph {
    int numVertices;
    struct Node* adjacencyList[MAX_VERTICES];
};

void initializeGraph(struct Graph* graph, int numVertices) {
    graph->numVertices = numVertices;

    for (int i = 0; i < numVertices; i++) {
        graph->adjacencyList[i] = NULL;
    }
}

void addEdge(struct Graph* graph, int src, int dest) {
    // 创建新节点
    struct Node* newNode = (struct Node*)malloc(sizeof(struct Node));
    newNode->vertex = dest;
    newNode->next = NULL;

    // 将新节点插入到源顶点的邻接表中
    if (graph->adjacencyList[src] == NULL) {
        graph->adjacencyList[src] = newNode;
    } else {
        struct Node* temp = graph->adjacencyList[src];
        while (temp->next != NULL) {
            temp = temp->next;
        }
        temp->next = newNode;
    }

    // 创建新节点
    newNode = (struct Node*)malloc(sizeof(struct Node));
    newNode->vertex = src;
    newNode->next = NULL;

    // 将新节点插入到目标顶点的邻接表中
    if (graph->adjacencyList[dest] == NULL) {
        graph->adjacencyList[dest] = newNode;
    } else {
        struct Node* temp = graph->adjacencyList[dest];
        while (temp->next != NULL) {
            temp = temp->next;
        }
        temp->next = newNode;
    }
}

void convertToAdjacencyMatrix(struct Graph* graph, int adjacencyMatrix[MAX_VERTICES][MAX_VERTICES]) {
    int numVertices = graph->numVertices;

    for (int i = 0; i < numVertices; i++) {
        struct Node* temp = graph->adjacencyList[i];

        while (temp != NULL) {
            int vertex = temp->vertex;
            adjacencyMatrix[i][vertex] = 1;
            temp = temp->next;
        }
    }
}

void printAdjacencyMatrix(int adjacencyMatrix[MAX_VERTICES][MAX_VERTICES], int numVertices) {
    printf("Adjacency Matrix:\n");
    for (int i = 0; i < numVertices; i++) {
        for (int j = 0; j < numVertices; j++) {
            printf("%d ", adjacencyMatrix[i][j]);
        }
        printf("\n");
    }
}

int main() {
    int numVertices, numEdges;
    printf("Enter the number of vertices and edges: ");
    scanf("%d %d", &numVertices, &numEdges);

    struct Graph* graph = (struct Graph*)malloc(sizeof(struct Graph));
    initializeGraph(graph, numVertices);

    printf("Enter the edges (src dest):\n");
    for (int i = 0; i < numEdges; i++) {
        int src, dest;
        scanf("%d %d", &src, &dest);
        addEdge(graph, src, dest);
    }

    int adjacencyMatrix[MAX_VERTICES][MAX_VERTICES] = {0};
    convertToAdjacencyMatrix(graph, adjacencyMatrix);

    printAdjacencyMatrix(adjacencyMatrix, numVertices);

    return 0;
}

在主函数中，首先输入图的顶点数和边数，然后输入每条边的起点和终点。算法将根据输入的邻接表构建邻接矩阵，并将结果打印出来。

请注意，以上代码仅为示例，需要根据实际需求进行修改和完善。
