Initializing multidimentional Array with a struct

[Chris Pons]

I'm trying to figure out how to initialize a multi-dimentional 
array with a struct. I thought it would be straight forward, but 
i'm running into problems. I'm using nested for loops, and just 
setting the current index to a blank version of my struct but 
that gives me this error: "Error: no [] operator overload for 
type Node". I didn't know I needed to overload that operator, 
usually didn't need to in C++ as far as I remember.

struct Node
{
    bool walkable;              
    vect2 position;             
    int xIndex, yIndex;
    Node*[4] connections;
}
void InitializePathGraph()
{
    for( int x = 0; x < mapWidth; x++ )
    {
        for( int y = 0; y < mapHeight; y++ )
        {
            Node node;
            PathGraph[x][y] = node;// ERROR
        }
    }
}
