如何访问二维数组

Question

我有一个图，它由一个二维数组表示：

int graph[9][9] = { {INFINITY, 4, INFINITY, INFINITY, INFINITY, INFINITY, INFINITY, 8, INFINITY},
                        {4, INFINITY, 8, INFINITY, INFINITY, INFINITY, INFINITY, 11, INFINITY},
                        {INFINITY, 8, INFINITY, 7, INFINITY, 4, INFINITY, INFINITY, 2},
                        {INFINITY, INFINITY, 7, INFINITY, 9, 14, INFINITY, INFINITY, INFINITY},
                        {INFINITY, INFINITY, INFINITY, 9, INFINITY, 10, INFINITY, INFINITY, INFINITY},
                        {INFINITY, INFINITY, 4, 14, 10, INFINITY, 2, INFINITY, INFINITY},
                        {INFINITY, INFINITY, INFINITY, INFINITY, INFINITY, 2, INFINITY, 1, 6},
                        {8, 11, INFINITY, INFINITY, INFINITY, INFINITY, 1, INFINITY, 7},
                        {INFINITY, INFINITY, 2, INFINITY, INFINITY, INFINITY, 6, 7, INFINITY} };

此图像这样作为 int *指针传递到我的班级

dijkstra::dijkstra(int* grapharray, int number_nodes)
{
    this->grapharray = grapharray;
    this->number_nodes = number_nodes;
}

为了访问数组，我做了一个变量

int** graph=&grapharray;

允许我访问

graph[0][2]
graph[0][5]

依此类推，但

graph[1][7]

如何在两个维度上访问图形？
