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. > substitutive constant is insanely large), the compiler would usually > give out a warning (if truncating) or an error straightaway. > > - Uday > - > To unsubscribe from this list: send the line "unsubscribe linux-c-programming" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > > +++++++++++++++++++++++++++++++++++++++++++ > This Mail Was Scanned By Mail-seCure System > at the Tel-Aviv University CC. >
