I'm sorry if I didn't pick a descriptive or concise name. A lot of questions sound similar, but I haven't been able to find what I'm looking for. What I want to do is store a 2D array of pointers somewhere and assign a variable in some object to that array to be able to access it.

Here's some example code that has the same compile error I'm getting with a bigger project.

#include <iostream>
using namespace std;
struct X{
    float * b[8][8];
    X(){
        *(b[1][5]) = 1;
        cout << *(b[1][5]) << endl;
    }
    void Set(float * c[8][8]){
        b = c;
        cout << *(b[1][5]) << endl;
    }
};
main(){
    float * a[8][8];
    *(a[1][5]) = 2;
    X obj;
    obj.Set(a);
}

What I want to happen in this code is that an X object starts with its own 2D array, whose value pointed to by b[1][5] should be printed as "1". Then the main method's 2D array, a, is passed to the object's Set() method and assigned to its array variable. The value pointed to by b[1][5] should then be printed as "2".

However, I can't figure out what type the Set() parameter, c, should be. I get

error: incompatible types in assignment of ‘float* (*)[8]’ to ‘float* [8][8]’

when I try to compile. As for why I want to do this, I'm trying to use an array of pointers to objects, not floats, but it's the same error.
