Nor have you. The definitions are as follows.

short <= int <= long
short < long
short > char

If your system does not conform to this, it isn't ISO (I thinhk it was ISO)
compliant.

What you stated above is true for (I would assume) all 32bit systems. It
will not necessarily hold for 64 bit or 128 bit systems.

I even had one person in the past try and tell me that when Intel went to
64bits, that M$ was going to have:

  short = 2 bytes
  long  = 4 bytes
  int   = 8 bytes

<rofl>
