Hmmmm.. I don't know why you would use a pointer to pointers to represent a
dynamically allocated 2 dimensional array in C++.

This appears that you are using a C-Style implementation.

 

The data structure you are trying to create appears to be a matrix. There
are several ways to accomplish this. I will take the C++ route,

and use a class with vectors to implement a matrix data structure. That
would be the C++ straight forward approach. Within this class

you could use templates so you could create a matrix with any C++ native
types and not just integers.

 

If you didn't want to do it by hand, the Boost library which I have
recommended to a lot of people on this list has it already done it for you.
