Complete Modern C++ - File IO - Part I (Basics)

The video tutorial explains the use of C++ file stream classes: ofstream, ifstream, and fstream for file input and output operations. It covers the inclusion of the fstream header file, the modes available for file operations, and how to check if a stream is open. The class hierarchy is discussed, highlighting the base class ios and its subclasses. The tutorial also demonstrates practical examples in Visual Studio, showing how to write to and read from files using these classes, and the use of the open function as an alternative to constructors.
