The language itself has no functions at all. All functions are either provided by a library or are user-defined. The C89 standard library has fewer than 200 functions but C99 has a few more. Although the standard library is considered part of the language, the library and the language are physically separate. However, the language does have built-in operators like sizeof() that are function-like. But unlike actual functions which are evaluated at runtime, these operators are evaluated at compile time.
If you have written it yourself, then it is the former, otherwise it is the latter.
This are the predefined functions in c, which are already write.Examples : printf(),scanf().
