built-in
(Or "primitive") A built-in function or operator is one provided by the lowest
level of a language implementation. This usually means it is not possible (or
efficient) to express it in the language itself. Typical examples are the basic
arithmetic and Boolean operators (in C syntax: +, -, *, /, %, !, &&, ||), bit
manipulation operators (~, &, |, ^) and I/O primitives. Other common functions
may be provided in libraries but are not built-in if they are written in the
language being implemented.
