cout is an object of class ostream that represents the
standard output stream. It corresponds to the cstdio stream
stdout.
By default, most systems have their standard output set to
the console, where text messages are shown, although this
can generally be redirected.
Because cout is an object of class ostream, we can write
characters to it either as formatted data using for example
the insertion operator (ostream::operator<<) or as
unformatted data using the write member function
Its an Object of class OStream, thats why we add its
corresponding header file that is <iostream.h>, Open this
