Could someone give me a once over on three dimensional vectors?
I need vectors because my array gets so big that it exceeds the stack size limit and I can't "delete" an element of an array. I am using a 3D array of long doubles, something like: 30x30x1000
Sample code would be great!
Thanks

You mean something like:

Code:

std::vector< std::vector< std::vector<long double> > > vec;
vec.resize(depth);
for(int y = 0; y < depth; y++) {
   vec[y].resize(height);
   for(int x = 0; x < height; x++) {
      vec[y][x].resize(width); 
   }
}

// output element at (i, j, k)
std::cout << vec[i][j][k] << std::endl;
