To say that "C treats a null byte as the end of a string" is a bit unfair. C barely knows what a "string" is. A large amount of C code
, including a great number of standard library functions, work with null-terminated strings. But that doesn't mean you can't write code that treats your own data however you like. Nothing is forcing you to stop at a null; there's just a certain class of pre-written functions that do so by convention
. If you know better (because, for example, your string is stored together with its length), then that's fine and well. C only cares about bits and bytes.
