ISTQB Certified Tester Advanced Level Technical Test Analyst Sample Questions:

1. 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 code contains data flow anomalies on lines 14 and 27. Which examples of data flow anomalies can be found on these lines?

A) Line 14: Cruise_Credits is defined but not subsequently used Line 27: Loyalty_Rating is not assigned a value (defined) before being used
B) Line 14: Cruise_Credits is not assigned a value (defined) before being used Line 27: Loyalty_Rating is defined but not subsequently used
C) Line 14: Cruise_Credits is re-defined before being used Line 27: Loyalty_Rating is defined but not subsequently used
D) Line 14: Cruise_Credits should not be declared as an integer Line 27: Loyalty_Rating should be calculated within the While loop
