How can I use bitwise operators in loops effectively?

Bitwise operators can optimize certain operations in loops, especially when dealing with binary data. For example, using the AND operator to check if a bit is set.

Can you give me an example of that?

Sure! If you want to check if the 3rd bit of a number is set, you can use: if (num & (1 << 2)) { // bit is set }.

What about using bitwise OR in loops?

Using bitwise OR can be useful for setting specific bits. For instance, num |= (1 << 2); sets the 3rd bit of num.

Are there any performance benefits to using bitwise operations?

Yes, bitwise operations are generally faster than arithmetic operations, especially in tight loops, as they operate directly on the binary representation.
