邻接矩阵：建立所给无向带权图的邻接矩阵存储并输出该矩阵

好的，您需要一个无向带权图的邻接矩阵。我可以为您提供一个简单的 Python 代码来实现这个功能。请注意，此代码假定节点从 0 到 n-1 标号。

# 定义邻接矩阵
adj_matrix = []

# 读取节点数和边数
n, m = map(int, input().split())

# 初始化邻接矩阵
for i in range(n):
    adj_matrix.append([0] * n)

# 读取每一条边，并将权值填入邻接矩阵对应位置
for i in range(m):
    u, v, w = map(int, input().split())
    adj_matrix[u][v] = w
    adj_matrix[v][u] = w  # 因为是无向图，所以需要对称填充

# 输出邻接矩阵
for i in range(n):
    for j in range(n):
        print(adj_matrix[i][j], end=' ')
    print()

您可以将此代码复制到 Python 编辑器中运行，然后输入节点数和边数以及每个边的起点、终点和权值，就可以得到所需的邻接矩阵。

很抱歉，我是一个语言模型AI，无法为您提供完整的C语言代码。但我可以给您提供一个参考：

1. 邻接矩阵：

#include <stdio.h>
#define MAX_VERTEX_NUM 100

typedef struct {
    int arcs[MAX_VERTEX_NUM][MAX_VERTEX_NUM];
    int vexnum, arcnum;
} Graph;

void createGraph(Graph *G) {
    int i, j, w;
    scanf("%d %d", &G->vexnum, &G->arcnum);
    for (i = 0; i < G->vexnum; i++) {
        for (j = 0; j < G->vexnum; j++) {
            G->arcs[i][j] = 0;
        }
    }
    for (i = 0; i < G->arcnum; i++) {
        scanf("%d %d %d", &i, &j, &w);
        G->arcs[i][j] = w;
        G->arcs[j][i] = w;
    }
}

void printGraph(Graph G) {
    int i, j;
    for (i = 0; i < G.vexnum; i++) {
        for (j = 0; j < G.vexnum; j++) {
            printf("%d ", G.arcs[i][j]);
        }
        printf("\n");
    }
}

int main() {
    Graph G;
    createGraph(&G);
    printGraph(G);
    return 0;
}

2. 邻接表：

#include <stdio.h>
#include <stdlib.h>
#define MAX_VERTEX_NUM 100

typedef struct ArcNode {
    int adjvex;
    struct ArcNode *next;
    int weight;
} ArcNode;

typedef struct VNode {
    char data;
    ArcNode *firstarc;

    scanf("%d %d", &G->vexnum, &G->arcnum);
    for (i = 0; i < G->vexnum; i++) {
        G->adjlist[i].data = i + 'a';
        G->adjlist[i].firstarc = NULL;
    }
    for (i = 0; i < G->arcnum; i++) {
        scanf("%d %d %d", &i, &j, &w);
        p = (ArcNode *)malloc(sizeof(ArcNode));
        p->adjvex = j;
        p->next = G->adjlist[i].firstarc;
        p->weight = w;
        G->adjlist[i].firstarc = p;
        q = (ArcNode *)malloc(sizeof(ArcNode));
        q->adjvex = i;
        q->next = G->adjlist[j].firstarc;
        q->weight = w;
        G->adjlist[j].firstarc = q;
    }
}

    int i;
    ArcNode *p;
    for (i = 0; i < G.vexnum; i++) {
        printf("%c ", G.adjlist[i].data);

            p = p->next;
        }
        printf("\n");
    }
}

void DFS(Graph G, int v, int *visited) {
    ArcNode *p;
    visited[v] = 1;
    printf("%c ", G.adjlist[v].data);
    p = G.adjlist[v].firstarc;
    while (p != NULL) {
        if (!visited[p->adjvex]) {
            DFS(G, p->adjvex, visited);
        }
        p = p->next;
    }
}

void BFS(Graph G, int v, int *visited) {
    Queue *rear, *front;
    ArcNode *p;
    rear = front = (Queue *)malloc(sizeof(Queue));
    front->next = NULL;
    visited[v] = 1;
    printf("%c ", G.adjlist[v].data);
    rear->data = v;
    rear->next = NULL;
    while (front->next != NULL) {

            }
            p = p->next;
        }
    }
}

    int visited[MAX_VERTEX_NUM];
    createGraph(&G);
    printGraph(G);
    DFS(G, 0, visited);
    printf("\n");
    BFS(G, 0, visited);
    printf("\n");
    return 0;
}

3. 最小生成树：

#include <stdio.h>
#define MAX_VERTEX_NUM 100
#define INF 32767

typedef struct {
    int arcs[MAX_VERTEX_NUM][MAX_VERTEX_NUM];
    int vexnum, arcnum;
} Graph;

void createGraph(Graph *G) {
    int i, j, w;
    scanf("%d %d", &G->vexnum, &G->arcnum);
    for (i = 0; i < G->vexnum; i++) {
        for (j = 0; j < G->vexnum; j++) {
            G->arcs[i][j] = INF;
        }
    }
    for (i = 0; i < G->arcnum; i++) {
        scanf("%d %d %d", &i, &j, &w);
        G->arcs[i][j] = w;
        G->arcs[j][i] = w;
    }
}

void prim(Graph G, int *lowcost, int *closest) {
    int i, j, k, min;
    for (i = 1; i < G.vexnum; i++) {
        lowcost[i] = G.arcs[0][i];
        closest[i] = 0;
    }
    for (i = 1; i < G.vexnum; i++) {
        min = INF;
        for (j = 1; j < G.vexnum; j++) {
            if (lowcost[j] < min && lowcost[j] != 0) {
                min = lowcost[j];
                k = j;
            }
        }
        printf("(%c, %c) ", closest[k] + 'a', k + 'a');
        lowcost[k] = 0;
        for (j = 1; j < G.vexnum; j++) {
            if (G.arcs[k][j] < lowcost[j]) {
                lowcost[j] = G.arcs[k][j];
                closest[j] = k;
            }
        }
    }
}

int main() {
    Graph G;
    int lowcost[MAX_VERTEX_NUM], closest[MAX_VERTEX_NUM];
    createGraph(&G);
    prim(G, lowcost, closest);
    return 0;
}
