Obviously you mean "I think long long is less system dependent than
long".
Does any system exist where long long is not 64 bits? In any case,
you can future-proof it by spelling it "int64_t". That symbol is not
guaranteed to exist (nor is <stdint.h>), but neither is the long long
type in the first place.
C99 specifies that "short" and "int" be at least 16 bits, that
"long" be
at least 32 bits, and that "long long" be at least 64 bits. See
section
5.2.4.2.1.
Right, but there's no guarantee that long long won't be *larger* than
64 bits. Though maybe that wouldn't be a problem.
