Handling Huge Multidimensional Arrays in C++

Question

I\'m designing a game in C++ similar to Minecraft that holds an enormous amount of terrain data in memory. In general, I want to store an array in memory that is [5][4][5][50][

Answer 1

A smaller example (with changed names for all the structs, to make the general principle clearer). The 'Bloe' struct is the one you want to allocate on the heap, and this is accomplished using 'new'.

   struct Bla {
        int arr[4][4];
   };

   struct Bloe {
        Bla bla[2][2];
   };

   int main()
   {
        Bloe* bloe = new Bloe();
        bloe->bla[1][1].arr[1][1] = 1;
        return 0;
   }
