FILES READ/WRITE -COMPLEX OPERATIONS

fstream is a standard C++ library that handles reading from and writing to files either in text or in binary formats. It is an object oriented alternative to C's FILE from the C standard library.

ifstream is the C++ standard library class that provides an interface to read data from files as input streams. The input stream may open a file in the constructor, just like an output stream. ifstream inf("input.dat", ifstream::in); //ifstream::in is a default, so it could be omited

or afterwards:

ifstream inf; inf.open("input.dat");

To close a stream, one uses the close method: inf.close();

The ifstream destructor will close the file cleanly as well. It is perfectly acceptable to allow the ifstream object to fall out of scope without calling close. This is often a desirable style, as it simplifies the "clean up" process when an exception is thrown or an error is otherwise encountered.
