A Gentle Introduction to C++ IO Streams One of the great strengths of C++ is its I/O system, IO Streams. As Bjarne Stroustrup says in his book "The C++ Programming Language", "Designing and implementing a general input/output facility for a programming language is notoriously difficult". He did an excellent job, and the C++ IOstreams library is part of the reason for C++'s success. IO streams provide an incredibly flexible yet simple way to design the input/output routines of any application. IOstreams can be used for a wide variety of data manipulations thanks to the following features: A 'stream' is internally nothing but a series of characters. The characters may be either normal characters (char) or wide characters (wchar_t). Streams provide you with a universal character-based interface to any type of storage medium (for example, a file), without requiring you to know the details of how to write to the storage medium. Any object that can be ...
