main() doesn't require any header file,
header files are not the part of C language they just
provides the means of accessing input/output and other
utilities.
int main()
{
int a=10;
return 0;
}
can be compiled without including any header file :)

Answer / sarita
main is not included in any header file
It is generally the first user-written function run when a
program starts .
main() is a function called by another function, which is
the start-routine. This routine is created by the compiler .
If you can write your own compiler, then you can think of
changing main() to your name itself!
ANSI compliant compilers need main() as the starting point.

header files does not contain main function.header files contains only input output functions and etc....
main is used for a indication of starting program.header files are checked before main execution.those are preprocessors.

Answer / tejas
main is the only function which is called from outside of the program. the code for invoking the main function is written inside something called as a "startup code". this startup code contains the prototype of main function. the main function is "called" from within this startup code which then is linked by linker to its definition created by the programmer. The linker, as we know, is responsible for linking object code to lib code. Along with these two codes, it also links startup code to create the executable file.
