0x0

"0x0" is a way of representing the number zero in hexadecimal notation, a base-16 numbering system used often in computing. The "0x" prefix indicates that the following characters are in hexadecimal format. In this case, "0x0" is simply zero expressed in hexadecimal form. It’s like writing a number in different languages; “0x0” and “0” both represent the same value, zero, but in different numeral systems. Hexadecimal is useful for computers because it aligns neatly with binary data, making it easier to read and interpret digital information.
