C++ Files

The fstream library allows us to work with files.

To use the fstream library, include both the standard <iostream> and the <fstream> header file:

There are three classes included in the fstream library, which are used to create, write or read files:

• ofstream - Creates and writes to files
• ifstream - Reads from files
• fstream - A combination of ofstream and ifstream: creates, reads, and writes to files
