A review of the following pseudo code is to be performed using a checklist:
Module Vowel Counter
Message: array of Characters
M, N: Integer
ACount, ECount, ICount, OCount, UCount: Integer
BEGIN
I=1
Read Nextchar
While Nextchar <> 'S'
DO
Message (I) = Nextchar
I = I+1
Read Nextchar
ENDWHILE
FOR M = 1 To I
DO
Print (Message(M))
IF Message (M) = 'E'
THEN
ECount = ECount + 1
ELSE
IF Message (M) = 'A'
THEN
ACount = ACount + 1
ELSE
IF Message (M) = 'I'
THEN
ICount = ICount + 1
ELSE
IF Message (M) = 'O'
THEN
OCount = OCount + 1
ELSE
IF Message (M) = 'U'
THEN
UCount = UCount + 1
ENDIF
ENDIF
ENDIF
ENDIF
ENDIF
ENDFOR
Print ('Message contains ' ACount + ECount + ICount + OCount + UCount ' vowels')
END
Which of the following checklist items would find code errors in this scenario?
A) Are all variables properly declared?
B) Are all loops, branches, and logic constructs complete, correct, and properly nested?
C) Are all cases covered in an IF-ELSEIF, including ELSE or DEFAULT clauses?
D) Are loop termination conditions obvious and invariably achievable?
E) Are there any redundant or unused variables?
