Input and Output Streams

Science is what we have learned about how to keep from fooling ourselves.

– Richard P. Feynman

In this chapter, we present the C++ standard-library facilities for handling input and output from a variety of sources: I/O streams. We show how to read and write files, how to deal with errors, how to deal with formatted input, and how to provide and use I/O operators for user-defined types. This chapter focuses on the basic model: how to read and write individual values, and how to open, read, and write whole files.
