The c program starts with 'main' function because it's compiler is designed that way. so during the compile time, the compiler looks for main function and through that it binds all the other user defined functions.


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).

What is pre-defined function in c?

Predefined functions in C are those that are part of the C library. These are present in any of the various headers that can be included in a program. For example, the function double sqrt(double) present in <math.h> that computes the square root of the argument passed to it.

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.
