If you wanted an infinite loop using numbers that are incrementing you could use itertools. • example: keep reading a value until the value is positive • such conditions are termination conditions – they indicate when the repetition should stop • However, loops in Java repeat actions while a condition is met. As an example, the C++ standard says that the compiler is allowed to assume that any loop will either terminate or make some globally-visible action, and so if the compiler sees the infinite loop it might just optimize the loop out of existence, so the loop actually does terminate.
