Algorithms for 2D arrays

[mighty asker]

Hello. Would you recommend me some good sources of algorithms for 2D arrays (merging, rotating, deleting rows, etc)?
P.S. What's the right way to declare an 2D array with the array library?

Declaring a 2D array is as simple as adding [][] to your desired object type.
for example:

string myStringArray[2][4];
int myIntArray[1][3];
double myDoubleArray[3][2];
char myCharArray[1][4];
etc....

I meant declaring like

array<int>myarr;

[anup30]

std::array<std::array<int,4>,12> data;

here data is 12x4 array of integers.

And same for vectors?
