Streams

  • All input and output is performed with streams.

  • A stream is a sequence of characters that are organized into lines, where each line consists of 0 or more characters and ends with the newline character, '\n'.

  • When execution begins, 3 streams are connected to the program, automatically.

  • Some operating systems, including both UNIX and DOS allow the standard input stream and the standard output stream to be redirected to other devices.

  • The standard error stream is typically used to print errors.
