hey-

EnderWiggin already explained how to do this using a 1 dimensional array.  
There is, however, a way to actually make a dynamic 2 dimensional array, 
though it does require a little more code.

Let's say you want an array with dims of A x B

you do something like this:

char * map[A];
for (int loop=0; loop < A; loop++)
     map[loop] = new char[B];

That will create a 2D array with size A x B, but as I mentioned before, it 
does take a little more code and time, which means it's not as efficient as 
Ender's solution.
