Pointer comparison

Do pointers in C and C++ support comparison operators (>, <, etc.) in standard?

I want to compare array positions to be precise.

Yes, they can be compared.

For example, see "Relational Operators" in standards for further information, 6.5.8 in C99, and 5.9 in old draft of C++ (2006-11).

In a contiguous array comparing memory offsets (pointers) is OK. If your array is implemented as a linked list (for example) the nodes could be all over memory so pointer comparison is nonsensical.
