How do you combine abstract classes with interfaces in C#?

Byyunus5454

Good morning, I have a question about comprehension. In C#, we have abstract classes, which are intended as base classes for more specific classes, and then we have interfaces, which serve as a kind of contract or specification. My question is, what would the structure look like if we wanted to combine interfaces and abstract…

DATA: pin_correct TYPE i VALUE 1234.

PARAMETERS lv_pin TYPE i.  

DO 3 TIMES.  
  IF lv_pin EQ pin_correct.
    WRITE 'Richtig'.      
    EXIT. " Aus der Schleife aussteigen
  ELSE.
   WRITE / 'Falsch, bitte nochmal eingeben'.
  ENDIF.
ENDDO.

IF sy-subrc NE 0.
  WRITE / 'Zu viele Versuche, Zugang abgelehnt'.
ENDIF.

But unfortunately, if I insert the PIN incorrectly, it will be spent 3 times wrong. So yes, no 3 attempts

Keep running your code to the right reporting time.
“AT SELECTION-SCREEN OUTPUT” was the event to get another input possibility.

Only the selection image is not processed in this way – i.e. the originally entered value is then tested 3 times.
