Actually the size of long int is 4 and the size of short is 2, the size
of int depends on the platform. With the old 16bit platforms (if you
can still find them ;-) it was 2 and with 32 bit machines its 4.

Int was supposed to be a word, but on 64bit machines that is not longer
stable.

with 64bits, a pointer is of size 8, but int and long can be either 4
or 8 and sometimes there is long long.

have look at http://en.wikipedia.org/wiki/64-bit.
