The externally observable consequences of calling a program on some input

The output of a program is the set of externally observable consequences of running a program on the given input.

A program's output can be manifested in several forms:

  1. What is printed to stdout and/or stderr
  2. What is written to an external file
  3. What changes are made to the inputs, which are then used in other functions or programs
