Does it mean
while (*r)
{
if (*r == '/')
{
n = r;
r++;
}
}
or
while (*r)
{
if (*r == '/')
{
r++;
n = r;
}
}
I think the second answer is the good one. It is more readable and
less error-prone than your example and the compiler will produce exactly
the same instructions. You don't need to do the work of the compiler; it
does it better. Better concentrate on writing programs easier to read
and less error-prone. These pre-increment and post-increment
instructions should be deprecated - I already advocated that on this
list, although it is not the place :-)
The reason why seasonned programmers prefer the kind of expression
you wrote, with post-increment, is a perfect example of a style dictated
by pure aesthetics. This an error I used to make when I was younger,
but, with age and learning, I have found true reasons to do otherwise.
