Pointer-to-pointer dynamic two-dimensional array

Question

First timer on this website, so here goes..

I\'m a newbie to C++ and I\'m currently working through the book \"Data structures using C++ 2nd ed, of D.S. Malik\".

Answer 1

In both cases your inner dimension may be dynamically specified (i.e. taken from a variable), but the difference is in the outer dimension.

This question is basically equivalent to the following:

Is int* x = new int[4]; "better" than int x[4]?

The answer is: "no, unless you need to choose that array dimension dynamically."
