What is the difference built in functions and user defined functions?

There are two types of functions in C++: Built-in or standard Library Function User defined function BUILT-IN FUNTION Built-in function which are also called Standard Library Functions are the functions provided by the C++ and we do not have to write them. These functions are included in the Header Files They are mostly written at the start of the Program They cannot be changed. EXAMPLE: conio.h; clrscrn; , etc. USER-DEFINED FUNCTION A user-defined function is a function defined by the programmer. It allows the programmer to write their own function. It allows the programmer to divide the program in many parts, which makes it easy for the programmer to rectify or modify the program; as it is easy to locate & jump to any part of the program. A programmer can write groups code to perform a specific task and that group of code is given a name (identifier).
