How do you pass 3D arrays through a constructor in C++?

My code so far:





class Grid {


private:


float data[100][100][100];





public:


Grid(float data_in[100][100][100]);


~Grid();


void drawDebug();


void draw();


};





Grid::Grid(float data_in[100][100][100]){


data = data_in; // %26lt;---Here lies the problem


};


Grid::~Grid(){};





void Grid::drawDebug(){};


void Grid::draw(){};





The problem shows up in the area marked with the comment. The compiler is treating the input parameter, data_in, as a type "float[][100][100]". I have no idea why it's dropping the size of the first dimension, but obviously it is unable to assign data_in to data because data is still a float[100][100][100].





Help greatly appreciated.

What you should do is declare data as:


float ***data;





then the constructor:


Grid::Grid(float ***data_in) {


data = data_in;





Then, somewhere, you should hold the size of the array. Probably a variable sent to your constructor.
Reply:I'm a little rusty in C++, but try the following.





data = %26amp;data_in;
