Is somebody define iostream header in simole and easy language

Question

define iostream language in simple language
if possible plz write in hindi

Answer 1

Header files are the sets of pre or post - defined library functions or in simple words you can consider it as a huge library of books, you can access the books which are present in the library and utilize them ,but you cannot utilize those books which are not available in that particular library.
In this case, the library is the header file and the books are its functions.
<iostream> is a header file which consist of some standard functions of c++ code such as cin and cout.
Without including <iostream> ,using cin and cout functions would be useless as the computer wont understand it.
I hope it helps.
