Hypercube with multidimensional vectors

Question

I\'m trying to implement a hypercubeclass, that is, multidimensional vectors. I have a problem generalizing it. I\'m able to make one for a three dimensional hypercube, but

Answer 1

I would suggest something along those lines:

template  class HQ {
  std::vector > vector;
  public:
    HQ(unsigned size) : vector(size,HQ(size)) {}
};

template  class HQ {
  std::vector vector;
  public:
    HQ(unsigned size) : vector(size,T()) {}
};

template  class HQ {};

You can then implement your accessors for the first both templates as you wish. You can also make things a bit more simple and robust by allowing zero-dimensional matrices:

template  class HQ {
  std::vector > vector;
  public:
    HQ(unsigned size) : vector(size,HQ(size)) {}
};

template  class HQ {
  T data;
  public:
    HQ(unsigned size) : data() {}
};

I imagine an access operator would look something like this:

template  HQ& HQ::operator[](unsigned i) {
  return vector[i];
}
template  HQ const& HQ::operator[](unsigned i) const {
  return vector[i];
}

such that you can write

HQ hq(5);
hq[1][4][2][0] = 77;
