That should be easy enough to remember now.

That table suggests that any program mixing 'short' and 'int' is
suspect.

To me it does not.  The table lists minimum values for all
implementations, and not the most common values for typical
implementations.

If 'int' doesn't need to store values beyond 16 bits, then
why not use 'short'?

I expect any developer who has spent even a fairly short time
learning C and writing C code knows the answer to this question,
and does not need to consult the table shown above to make an
appropriate choice between 'int' and 'short' in each of the
circumstances where the question may occur.
