std::basic_ifstream::close - std::basic_ifstream::close
void close();
Closes the associated file.
Effectively calls rdbuf()->close(). If an error occurs during operation,
setstate(failbit) is called.
This function is called by the destructor of basic_ifstream when
the stream object
goes out of scope and is not usually invoked directly.

Reason: no example
is_open checks if the stream has an associated file
(public member function)
open opens a file and associates it with the stream
(public member function)
close flushes the put area buffer and closes the associated file
(public member function of std::basic_filebuf<CharT,Traits>)
