What does a bitwise shift (left or right) do and what is it used for?

Question

I\'ve seen the operators >> and << in various code that I\'ve looked at (none of which I actually understood), but I\'m just wondering

Answer 1

Yes, I think performance-wise you might find a difference as bitwise left and right shift operations can be performed with a complexity of o(1) with a huge data set.

For example, calculating the power of 2 ^ n:

int value = 1;
while (exponent

Similar code with a bitwise left shift operation would be like:

value = 1 << n;

Moreover, performing a bit-wise operation is like exacting a replica of user level mathematical operations (which is the final machine level instructions processed by the microcontroller and processor).
