I just checked and Microsoft's C++ compiler does not do this optimization, but it does if you do:

What are bitwise shift (bit-shift) operators and how do they work?
...t; is not an operator, because it would be redundant.
Also note that C and C++ do not distinguish between the right shift operators. They provide only the >> operator, and the right-shifting behavior is implementation defined for signed types. The rest of the answer uses the C# / Java operat...
