Question

Console.WriteLine(7 << 4);
Console.WriteLine(7 >> (32 - 4));

For some reason the second method returns 0 instead of 112. But they both should be equal to one another, they both should return 112.

UPDATE:
It’s known that (x << n) == (x >> (32 - n)).

Your ideas?

Answer 1

Don’t really understand what you expect to see here:

7 << 4 is shifting left (like multiplication) 7 * (2 ^ 4) = 7 * 16 = 112

on another hand

7 >> (32 - 4) is shifting right (like division)7/(2^28), that converted to integer value leads to 0.

The question is why Console.WriteLine peaks integer overload: is cause you act on integer values so expected by CLR result is int.

So result is correct.
