An "infinite loop" is a loop in which the exit criteria are never satisfied; such a loop would perform a potentially infinite number of iterations of the loop body. The general problem of determining whether the execution of a loop with given preconditions will result in an infinite loop is undecidable; in other words, there is no algorithm to determine whether an execution of a loop will eventually terminate. This is known as the halting problem.
