Question
What does a bitwise shift (left or right) do and what is it used for?
Some examples:
Bit operations for example converting to and from
Base64
(which is 6 bits instead of 8)
doing power of 2 operations (
1 << 4
equal to
2^4
i.e. 16)
Writing more readable code when working with bits. For example, defining constants using
1 << 4
or
1 << 5
is more readable.
