Dimension-independent loop over boost::multi_array?

Question

Say I\'ve got an N-dimensional boost::multi_array (of type int for simplicity), where N is known at compile time but can vary (i.e. is a non-type template param

If you don't need the index, you can simply do:

  for (unsigned int i = 0; i < A.num_elements(); i++ )
  {
    tValue item = A.data()[i];
    std::cout << item << std::endl;
  }
