Q: 6
Below is pseudo-code which calculates a customer's cruise credits based on past cruise history:
PROGRAM CALC CRUISE CREDITS (CUST_ID)
COUNT_CRUISES, CRUISE_CREDITS, LOYALTY_RATING: INTEGER
CRUISE_LENGTH, CRUISE_ACCOM_TYPE: VAR
LOYALTY_RATING = 0
COUNT_CRUISES = 0
CRUISE_LENGTH = 0
CRUISE_ACCOM_TYPE = 0
BEGIN
READ CUSTOMER'S CRUISE HISTORY TO OBTAIN COUNT OF CRUISES
READ CRUISE_HISTORY (CUST_ID)
WHILE COUNT_CRUISES != -1 DO
READ CUSTOMER'S NEXT CRUISE
READ NEXT_CRUISE
IF CRUISE_ACCOM_TYPE = 3 THEN
CRUISE_CREDITS = CRUISE_CREDITS + 5
ELSE
IF CRUISE_ACCOM_TYPE = 2 THEN
CRUISE_CREDITS = CRUISE_CREDITS + 3
ELSE
CRUISE_CREDITS = CRUISE_CREDITS + 2
ENDIF
ENDIF
COUNT_CRUISES = COUNT_CRUISES - 1
ENDWHILE
LOYALTY_RATING = CRUISE_CREDITS / COUNT_CRUISES
WRITE ("CRUISE CREDIT TOTAL IS:")
WRITE (CRUISE_CREDITS)
END PROGRAM CALC CRUISE CREDITS
The variable Cruise_Length (line 3) results in which type of data flow anomaly?
