Reshaping a 1-d array to a multidimensional array

Question

Taking into consideration the entire C++11 standard, is it possible for any conforming implementation to succeed the first assertion below but fail the latter?

Answer 1

I am under the impression that it will work. You allocate the same piece of contiguous memory. I know the C-standard guarantees it will be contiguous at least. I don't know what is said in the C++11 standard.

However the first assert should always be true. The address of the first element of the array will always be the same. All memory address will be the same since the same piece of memory is allocated.

I would therefore also say that the second assert will always hold true. At least as long as the ordering of the elements are always in row major order. This is also guaranteed by the C-standard and I would be surprised if the C++11 standard says anything differently.
