用C写一下迪杰斯特拉算法

好的，以下是用C语言实现迪杰斯特拉算法的代码：

#include <stdio.h>
#include <limits.h>

#define V 9

int minDistance(int dist[], bool sptSet[]) {
    int min = INT_MAX, min_index;

    for (int v = ; v < V; v++)
        if (sptSet[v] == false && dist[v] <= min)
            min = dist[v], min_index = v;

    return min_index;
}

void printSolution(int dist[]) {
    printf("Vertex \t Distance from Source\n");
    for (int i = ; i < V; i++)
        printf("%d \t\t %d\n", i, dist[i]);
}

void dijkstra(int graph[V][V], int src) {
    int dist[V];
    bool sptSet[V];

    for (int i = ; i < V; i++)
        dist[i] = INT_MAX, sptSet[i] = false;

    dist[src] = ;

    for (int count = ; count < V - 1; count++) {
        int u = minDistance(dist, sptSet);

        sptSet[u] = true;

        for (int v = ; v < V; v++)
            if (!sptSet[v] && graph[u][v] && dist[u] != INT_MAX && dist[u] + graph[u][v] < dist[v])
                dist[v] = dist[u] + graph[u][v];
    }

    printSolution(dist);
}

int main() {
    int graph[V][V] = {{, 4, , , , , , 8, },
                       {4, , 8, , , , , 11, },
                       {, 8, , 7, , 4, , , 2},
                       {, , 7, , 9, 14, , , },
                       {, , , 9, , 10, , , },
                       {, , 4, 14, 10, , 2, , },
                       {, , , , , 2, , 1, 6},
                       {8, 11, , , , , 1, , 7},
                       {, , 2, , , , 6, 7, }};

    dijkstra(graph, );

    return ;
}

希望这个回答对你有帮助！
