What does this mean? I'm having trouble parsing this as English much less making sense of the argument :)

Why does libc ship with string functions in the first place? What is special about strings that they are included in libc while other data structures (to my knowledge) are not? Presumably you don't need strings to implement malloc or other parts of libc?
- saagarjha 7y agoStrings ship with libc because pretty much every language ships with string manipulation routines. You need them to basically do anything that isn’t pure computation.
- _kst_ 7y agolibc includes string functions because C requires string manipulation functions. Other languages may or may not make use of C's string functions.
- saagarjha 7y agoYes, because they ship with their own string type.
- weberc2 7y agoGranted, but pretty much every language also ships with routines for other data structures, and I would think that you need things like lists/slices more often than you need string routines.
