Vector of multidimensional arrays

Is there a way to make vectors of multidimensional arrays? im trying to create a vector with 2-dimensional integer arrays as its elements, but vector<int[4][4]>does not work. What is the right way to do this?

You cannot have array vectors. Standard container item types must be copyable, and arrays cannot be copied.

However, you can have a vector of vectors, for example:

std::vector<std::vector<int> >

Play with it.

Or to stick with arrays:

std::vector<boost::array<int, N> >

Or if you have C ++ 0x:

std::vector<std::array<int, N> >

{boost,std}::array - This is a wrapper of objects around arrays of automatic storage duration, so it is pretty close to what you originally tried to execute.

As @vrince explained in a comment, you can create a class / structure encapsulation int[4][4]:

struct My2DArray {
  int a[4][4];
};

And declare vectorfor above:

vector<My2DArray> obj;

For convenience, you can define various methods operatorand public(for example, copy constructor, assignment operator, etc.) to deal with it.
