# Does a coin tossing algorithm terminate? [duplicate]

Suppose we have an algorithm like:

n = 0
REPEAT
c = randomInt(0,1)
n = n + 1
UNTIL (c == 0)
RETURN n


(Assumuing the random number generator produces "good" random numbers in the mathematical sense.)

I understand that there is no number $n \in \mathbb{N}$ such that the algorithm is guaranteed to terminate after fewer than $n$ steps. However, the probability of terminating after some finite number of steps is 1.

Is there a convention among computer scientists to call an algorithm like this either "terminating" or "non-terminating"?
