Yes, this is true. However, the only time this matters is when your function
arguments have a side effect; when this occurs in more than one argument; and
when the side effect interact. This allows the compiler to optimise for the
common case at the expense of a rare case.

You are an experienced Fortran programmer who has learned to speak C
fluently. You don't think in it, as is demonstrated by your frequent
postings flaming about this or that aspect of C that offends you.

I think it's time for comp.lang.jim-giles-and-herman-rubin.
