in header files whether functions are declared or defined in c language?..

Answer / suraj.v

in header files the function are declared not defined it's
defined in the library routines
only A header file is a file containing C declarations and
macro definitions to be shared between several source files.

You request the use of a header file in your program by
including it, with the C preprocessing directive `#include'.

Header files serve two purposes.

1) System header files declare the interfaces to parts of
the operating system. You include them in your program to
supply the definitions and declarations you need to invoke
system calls and libraries.

2) Your own header files contain declarations for interfaces
between the source files of your program. Each time you have
a group of related declarations and macro definitions all or
most of which are needed in several different source files,
it is a good idea to create a header file for them.
