The LL makes the integer literal of type long long. So 2LL, is a 2 of type long long. With just the literal 1, (assuming int to be 32-bits, you shift beyond the size of the integer type -> undefined behavior). With 1LL, you set the type to long long before hand and now it will properly return 2^40. That's a great explanation. how do i check a car title
