Casting to unsigned char for isupper() and friends

I can remember raising it, which is why my comment above.

Ah well - so much for the length of my recall.

But I see no point to arguing about it.

Nor I.

I simply stated my opinion.

"follow it with a blank" doesn't, to my mind, have the ring of a
statement of opinion. It sounds more like an instruction.

True, but else is seldom a problem. I don't think I've ever seen an
else immediately followed by a left parenthesis. At least, I hadn't
until a couple of minutes ago, when I write this silly little program:

#include <stdio.h>
int main(int argc, char **argv)
{
if (argc == 1)
puts("No arguments");
else(puts("One or more arguments"));
return 0;
}

(Or I could have added a cast to void rather than enclosing the entire
call in parentheses.)

Why the hell?
else puts("One or more arguments");
wasn't fine enough?

It wouldn't have been a demonstration of "else immediately followed by a
left parenthesis", that which Keith hadn't seen until he wrote it - as
is evident in the text I (and you) quoted.

Look at the prefix.

The latter. sizeof is not a function. Consistency pays.

What about
(int)
vs.
( int )
?
