long long is a signed integer type
with the range LLONG_
to LLONG_,
which is at least ±9223372036854775807. It can also be called
signed long long or long long signed. Use %lld or
%lli with printf to print an long long. Use %lld or
%lli with scanf to scan an long long. Constants of type
long long are suffixed with
ll or LL.
unsigned long long is an unsigned integer
type with the range 0 to
ULLONG_, which is at least
+18446744073709551615. It can also be called long long unsigned. Use %llu,
%llo, %llx or %llX
with printf to print an unsigned long long. Use %llu,
%llo or %llx with scanf to scan an unsigned long long. Constants of type
unsigned long long are suffixed with
ull, Ull,
llu, llU,
uLL, ULL,
LLu or LLU.
sizeof(long long) and sizeof(unsigned long long) are the same. long long and unsigned long long are intended to be wider
than other standard native integer types like long.
atomic_
is an alias for _Atomic unsigned long long. atomic_
is an alias for _Atomic long long. These types are lock-free always if
ATOMIC_ is
2, sometimes if 1, and never if 0.
