Largest possible value of Integer Constants

[Nicholas]

How can I get the largest possible value of the Integer Constants and use it
in the program for these types:
1. int
2. long
3. unsigned short

Thanks

#include <limits.h>

INT_MAX, LONG_MAX, USHRT_MAX. And many more.

See http://www-ccs.ucsd.edu/c/limits.html .

To the OP: also note that if portability is one of your objectives, you
will want to use the minimal required values for those limits as
specified in the ISO C standard (e.g. 65536 for UINT_MAX, etc.).
Tom: nitpick. Your sig block looks ok, but is not (else it would have
been automatically cut away by my newsreader...): you need to have an
additional space character after those two dashes that start your sig block.

Ah. I wondered why that space was there. Is that in an RFC or
something?

Maybe he has, but his posting software was written in C ;-)

Whether space characters that are written out immediately before a
new-line character appear when read in is implementation-defined.

Requiring a space right before the end of the line in the sig block
separator was a brain dead idea in the first place. The posting software
I've used until this year simply dropped that space.

Are you saying that's part of the C standard? In what context?
It's hard to believe that's part of the standard - what if binary
data happens to contain \x20\x0a?

Anyway, my posting software (Netscape) isn't at fault. It precedes
a sig with "-- \n". I put "--\n" inside my sig block to separate
the sig I use for email from the sig I use when spammers will see
it.

It only applies to text streams, not binary streams.

! I wasn't aware that C made a distinction. Have to read more...
