When should I use bitwise operators instead of arithmetic operators?

Bitwise operators are used for manipulating individual bits of data, while arithmetic operators perform mathematical calculations. You should use bitwise operators when you need to perform operations like AND, OR, XOR, or NOT on binary representations of numbers.

Can you give me an example of when to use a bitwise operator?

Sure! If you want to check if a specific bit is set in a number, you can use the bitwise AND operator. For example, to check if the 3rd bit is set in the number 5 (which is 101 in binary), you can do 5 & 4 (which is 100 in binary). If the result is 4, then the 3rd bit is set.

What about performance? Are bitwise operations faster?

Yes, bitwise operations are generally faster than arithmetic operations because they operate directly on the binary representation of numbers without the overhead of arithmetic calculations. However, the performance difference may be negligible for most applications.

Are there any situations where I should avoid using bitwise operators?

Yes, you should avoid using bitwise operators when working with floating-point numbers or when the logic becomes too complex, as it can make your code less readable and harder to maintain.
