I agree, and thanks for all the corrections on my posts with my
limited knowledge on the C standard.

Since we deal with mostly Windows (desktop + many variants of CE) and
Linux (many variants of desktop + many variants of embedded Linux),
and our code happens to be in C and C++, we are looking for people who
are at least familiar with the concept of memory layout as described
in the following.

Since we also deal with many compilers, some of which do not comply
with "the standard", we are (at least I am) slacking quite a bit on
the correct definition of C :)

At the end of the day, the answer "implementation-specific" to OP is
wise and correct, but it will unlikely satisfy the interviewer. The
expected answer is to describe the "general" memory layout of a
process, given the simple, yet subtle question asked in C. And never
heard of "stack/heap" is sort of a no-no :)

Cheers!
