Like the cstdio header inherited from C's stdio.h, iostream provides basic input and output services for C++ programs. iostream uses the objects cin , cout , cerr , and clog for sending data to and from the standard streams input, output, error (unbuffered), and log (buffered) respectively.

Hey!
iostream.h is most important header file for basic input and output operations. iostream.h contain built-in functions cout and cin for input-output. So, every C++ program should include iostream.h header file for performing input and output operations.
