Schematic-wise, output = input = DC voltage with a ripple. Simply because it's connected, that is: output & input is 1 electrical point, and thus has the same voltage at all times.
In a real-world circuit, capacitor would have a filtering effect because voltage sources are never ideal.
So answer really depends on whether this is about an existing/practical circuit, or whether this is about the theoretical circuit (with ideal components) as represented by the schematic. In the latter case, Ratch gave the answer.
