NAME
       cerr

	-  Controls  output to an unbuffered stream buffer associated with the
       object stderr declared in <cstdio>.

SYNOPSIS
       #include <iostream>
       extern ostream cerr;
       ostream cerr;

DESCRIPTION
       The object cerr controls output to an unbuffered stream buffer  associ‐
       ated with the object stderr declared in <cstdio>. By default, the stan‐
       dard C and C++ streams are synchronized, but you	 can  improve  perfor‐
       mance  by using the ios_base member function synch_with_stdio to desyn‐
       chronize them.

FORMATTING
       The formatting is done through member functions	or  manipulators.  See
       cout or basic_ostream for details.

EXAMPLE
       //
       // cerr example
       //
       #include<iostream>
       #include<fstream>

       void main ( )
       {
 using namespace std;

  // open the file "file_name.txt"
  // for reading
 ifstream in("file_name.txt");

  // output the all file to stdout
 if ( in )
   cout << in.rdbuf();
 else
    // if the ifstream object is in a bad state
    // output an error message to stderr
   cerr << "Error while opening the file" << endl;
}
