1)are library/header files essential elements in "C" programming
such as,
#include<stdio.h>
#include<conio.h>
--------------------------------------------------
2)is there any relation between modules in perl/python and library/header files in "C" ????

1) Short answer, yes.

Without them programming in C would become nasty. Even the simple printf() function has a lot of work to do for printing a line at the screen and I mean a lot. Try and debug a program and follow it inside the declaration of printf() you will see that there are a ton of lines just for that. Imagine typing the same lines for every time you would want to print something on the screen...

This little sample gives a good idea about the use of header files. They help writing clean code and dividing big complex program to smaller easier to handle logical pieces.

2) Although there are differences between them the concept remains the same.
