Answer / jyoti
header file is a preprocessor directive that contains all
the functions thet we have to use in our program and has to
be declared before the main function.
ex: headerfile <stdio.h> include functions such as printf()
and scanf() that puts the output and gets the input
repectively

Include directory is special directory which content all the
header files of c language. Extension of header files in c
language is header. All header files only keep declaration of
functions, declaration of data type and micro constants. Body
of function i.e. function definition is not written in the
header files. Hence no one can get source code of function
like printf, clrscr etc. All the function declaration in
header file is extern. Since visibility of extern data type is
whole the program. and other file can also access such
function. Body of function of header file is supplied at the
time of linking in header file.
