Hi Nelson, >> ... >> I'd have thought that on a 64-bit word-size architecture, int would be >> 64-bits big, long would be 128-bits big, and long long would be >> 256-bits big. >> ... > No, the only requirement on C's integer data types is that > > sizeof(char) <= sizeof(short) <= sizeof(int) <= sizeof(long) <= sizeof(long > long) I'm aware of the minimum size requirements of the types, as per ISO 9899 or ISO 14882. There are also semantic expectations of the data types, but those are not expressed in the standard. They are left to the implementer of the compiler on the given architecture and operating system. I was expressing my expectations. Hence the "I'd have thought..." preface. Is there a "Design & Evolution of C", something akin to Stroustrup's "Design & Evolution of C++"? Sincerely, --Eljay
