(.h)means a header file,
and all the header files r included using
#include which is a preprocessor directive
i.e #include<stdio.h>
all the data input/output functions r stored in stdio.h
(where std-standard i-input o-output)
for eg.printf,scanf,putchar,getchar,puts,gets..

#include<conio.h>
(where con-console i-input o-output)
for eg.getch(),clrscr()...
there r many header files for diff purposes
like

#include<math.h> for maths

#include<iostream.h> for streams
etc........
