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. iostram.h...

iostream is just a header file where all the input output stream related functions are written. when you use iostream.h , you can use all prewritten functions of that e.g you don't define cin or cout anywhere in your function, but still you can use them , its because what they have to do is already written...

iostream means Input Output STREAM hence iostream is used for input output purposes.it might also provide them in the global name-space just as stdio.h might provide them in namespace std, cin and cout are the object part of iostream.h.

iostream - operates on characters of type char iostream contains the definition of basic_iostream class template, which implements formatted input and output C++ input/output streams are primarily defined by iostream, a header file that is part of the C++ standard library (the name stands for Input/Output Stream). In C++ and its predecessor, the C programming language, there is no special syntax for streaming data input or output. Instead, these are combined as a library of functions. 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. As part of the C++ standard library, these objects are a part of the std namespace. read less
