I have this question but I don't know what happen to a dff without an input is it always 0 ?? like this picture below the 2nd dff hasn't any d ??? Also, if someone can draw the answer of the question ? thank you
and I would like t

After the asynchronous reset is deasserted and the first rising clock edge occurs, the flip-flop's state will generally be indeterminate. The only way the state could have a known value is if the flip-flop's inputs have a known value when they are unconnected, due to the specific circuitry involved. For example, true TTL logic inputs would default to a high logic level if left unconnected.
