Text I/O

Input and output have two basic flavors: text and binary. Binary I/O introduces subtleties that are beyond the scope of this book, so all discussion of I/O herein is text-oriented. This Exploration presents a variety of topics related to textual I/O. You’ve already seen how the input and output operators work with the built-in types as well as with the standard library types, when it makes sense. You’ve also seen how you can write your own I/O operators for custom types. This Exploration offers some additional details about file modes, reading and writing strings, and converting values to and from strings.
