A subprogram with side effects may return different results each time it is called
question: Can a subroutine return a different result when it is called?, context: A subroutine call may also have side effects such as modifying data structures in a computer memory, reading from or writing to a peripheral device, creating a file, halting the program or the machine, or even delaying the program's execution for a specified time. A subprogram with side effects may return different results each time it is called, even if it is called with the same arguments. An example is a random number function, available in many languages, that returns a different pseudo-random number each time it is called. The widespread use of subroutines with side effects is a characteristic of imperative programming languages.
