Write in Pascal is an example: it doesn't come from a library, it is built-in into the compiler.

Function. Use the built-in help for details.

The default function is built inside of Python.


What is built-in function in c?

There are no built-in functions in C++. The definition of a built-in function is a function that does not need to be declared before it is used, but every function in C++ is user-defined and must be declared before it can be used. This includes functions provided by the C++ standard library which we declare by including the appropriate headers.Some articles mistakenly describe keywords such as while, switch and if as being built-in functions, however these are statements, not functions.C++ does provide several built-in operators, some of which look and behave very much like functions. For example, the built-in sizeof() operator can be used without any declaration and looks very much like a function, but its argument is not a value, it is a type name, and we cannot (easily) define a function that accepts a type name as an argument.The built-in typeid() operator also takes a type name argument, but it is often mistakenly regarded as being a user-defined function because we must include the C++ standard library header in order to use it. But that header is only required because the return value is a std::typeinfo object which is not a built-in data type.Unlike sizeof() and typeid(), the default global new and delete operators can be overridden with user-defined function operators, thus these are also mistakenly regarded as being built-in functions. However, only the overrides are functions because that's the only way to define an operator overload; the default global operators are built-in operators, not built-in functions.The semantic difference between a built-in operator and a built-in function may seem insignificant, however a real built-in function would be no different to a user-defined function other than the fact that it need not be declared before using it. But a user-defined function also has identity (a memory address) and we can pass that identity to other functions using a function pointer argument. But we cannot pass a built-in operator to a user-defined function because it has no identity, thus it cannot be regarded as being a built-in function.


Is the main function in C a built-in function or user-defined function?

The main function in C is user-defined. Built-in functions are simply those that do not require a library to be included, but every program must provide a user-defined point of entry; it cannot be built-in. Indeed, most functions in C are user-defined; the built-in functions are mostly operators rather than functions although most do behave like functions. The standard library functions are not built-in either; they all require the inclusion of the appropriate standard library header.
