WebDec 7, 2015 · 17. When you shift a value by more bits than word size, it usually gets shifted by mod word-size. Basically, shifting it by 64 means shifting by 0 bits which is equal to no shifting at all. You shouldn't rely on this though as it's not defined by the standard and it can be different on different architectures. Share. WebIt is worth to add some explanation on what others have pointed out: Bitwise shifting a bool is casted into int.. bool b = true; bool d = b << 1; printf("%d\n", d); This code snippet prints 1 on the screen not 0.The reasoning is that b << 1 is casted to int which is 2 (binary 10).The result is then casted to bool.The latter casting would be 0 if the value of the int is 0 and 1 …
