Question

i know how to create a stack of vectors or int ,etc. But i dont know how to create a stack of a multidimentional arrays t[n][n] . Whats the way to implement it?
this is my actual implementation which its not working.

char map[20][20];
stack<map> soluciones;

Edit:

I think due my english most of you didnt undestand my question. Imagine i got some kind of a Game map. I am saving each multidimentional array on the stack. Thats my objective saving the map on a stack

Edit 2: im using Visual Studio 2010 Windows form application

In your code example, you use map (the name of your variable) in place of where a type name must stand (in stack<map> template instantiation). However, it won’t work, not even if you use the proper type name (in this case you’d have to use typedef, e.g. typedef char TwoDimCharArray[20][20] and then try std::stack<TwoDimCharArray>:

There is still the problem that arrays don’t have a default constructor (which std::stack expects); therefore, std::stack cannot be made to directly contain arrays; you’d have to wrap the array inside a class or struct (which can have a default constructor), e.g.:

class TwoDimCharArray
{
public:
    // omit if there's nothing to initialize in map, then the
    // compiler-generated constructor will be used
    TwoDimCharArray()
    {
        // ... initalize map values
    }
    // ... provide access methods to map
private:
    char map[20][20];
};

std::stack<TwoDimCharArray> soluciones;

Or use Boost.Array or C++11 std::array stuff! If these are available, they are definitely the better and easier choice!
