multidimensional arrays

[asdf]

I was told not to use the low-level language such as arrays which
inherited from C, I want to know what can I use to substitute the
C-style multidimensiona l arrays? Is there multidimensiona l vector?

E.g.,

std::vector< std::vector< int

There are boost library

http://www.boost.org/libs/multi_array/doc/user.html#sec_introduction

see if it fits your needs.

The usually way is to do a vector of vectors, but I find that troublesome,
and usually wind up encapsulating the 2nd vector. Something like:

struct MyList
{
std::vector<int IntVector;
};

std::vector<MyL istMy2DArray;

I just find the syntax a bit easier than
std::vector<std ::vector<int My2DArray;

Why use a struct here, why not just do
typedef std::vector<int MyList;

std::vector<MyL istMy2DArray;

Long live inefficient code!
