QUESTION 8:
AGE contains 77. Which of the two boxes (contained inside a larger box) will execute?
If AGE is 77, the false branch is chosen:
PRINT "Enter full fare" INPUT FARE PRINT "Enter age" INPUT AGE ' 'Calculate discount based on age IF AGE < 12 THEN <-- false +------------------------------------------------+ | LET RATE = 0.0 | +------------------------------------------------+ ELSE +------------------------------------------------+ | IF AGE < 24 THEN | | LET RATE = 0.70 | | | | ELSE | | | | IF AGE < 65 THEN | | LET RATE = 1.0 | | ELSE | | | <-- false branch | LET RATE = 0.75 | chosen | | | END IF | | | | | | END IF | +------------------------------------------------+ END IF 'Calculate fare PRINT "Your fare is:", FARE * RATE END
The false branch has been picked; zoom in on just it and remember that it acts like a little program:
+------------------------------------------------+ | IF AGE < 24 THEN | | +---------------------------------------+ | | | LET RATE = 0.70 | | | +---------------------------------------+ | | ELSE | | +---------------------------------------+ | | | IF AGE < 65 THEN | | | | LET RATE = 1.0 | | | | ELSE | | | | | | | | LET RATE = 0.75 | | | | | | | | END IF | | | +---------------------------------------+ | | | | END IF | +------------------------------------------------+
The little program itself contains an IF statement with its own true and false branches. Those branches have been put into boxes.
