What are some real-world examples of bitwise operators?

Bitwise operators are used in various applications, such as image processing, network programming, and cryptography. For instance, in image processing, bitwise operations can help manipulate pixel values for effects like masking or blending.

Can you explain how bitwise operators are used in image processing?

Sure! In image processing, bitwise operators like AND, OR, and XOR can be used to combine images or create masks. For example, using the AND operator can help isolate certain parts of an image by turning off pixels that don't meet specific criteria.

What about their use in network programming?

In network programming, bitwise operators are often used for manipulating IP addresses and subnet masks. For example, the AND operator can determine if an IP address belongs to a specific subnet by comparing the address with the subnet mask.

Are there any examples in cryptography?

Yes, in cryptography, bitwise operators are used in algorithms for encryption and decryption. For instance, XOR is commonly used in stream ciphers to combine plaintext with a key, ensuring that the output is secure.
