Question

I can't understand what is <iostream> in C++?

Answer 1

Hey Pranab ,
Iostream is a library in c++ for input and output .
iostream header is used to access the input and output built in function of the language it is the "standard input / output stream library " .
iostream which has 1000s of source code which gives access to input and output
such as you can print on screen that's just by istream and you can take inputs by keyboard by ostream ...
these library function interacts to ur system . its a tedious task every times to write input and output codes .. so c++ have some standard libraries to make life easy !!!

Answer 2

Input output stream, a collection of functions for standard input and output. Just code wrote by other people.
