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...

...
is a commonly seen pattern but it's different from
for(int i; ...)
in C++ in that that the variable isn't scoped to the for block. In fact, the var gets hoisted to the top of the enclosing scope (function) so a local i will be effectively available both before the for loop (after the beginning...
