‘Comment 90-100 = A 80-89 = B 70-79 = C 60 – 69 = D Under 60 = F INPUT: Student name, Raw Exam Score One, Raw Exam Score Two, Raw Exam Score Three OUTPUT: Student name "received a grade of” Letter grade (based on average of three scores) VARIABLES: NAME, S1, S2, S3, AS, GRADE Pseudocode Start Read NAME, S1, S2, S3 AS = (S1 + S2 + S3) / 3 IF AS => 90 AND AS =< 100 THEN GRADE = A ELSE IF AS => 80 AND AS =< 89 THEN GRADE = B ELSE IF AS => 70 AND AS =< 79 THEN GRADE = C ELSE IF AS => 60 AND AS =< 69 THEN GRADE = D ELSE IF AS < 60 THEN GRADE = F ENDIF ENDIF ENDIF ENDIF Write Write NAME, “received a grade of ", GRADE Stop Or will the division of three require an integer or double?

    An integer for Variable AS will ensure that the grade is picked up, if your using F90 or (hopefully) something newer then a case statement is much more appropriate for this problem. If AS is an integer then, it will round to the nearest integer when assigned a single or double precision number., such as the group grade. Select Case AS Case IS < 60 Grade = F Case 61 to 69 Grade = D Case 70 to 79 Grade = C Case 80 to 89 Grade = B Case 90 to 100 Grade = A Case Else Print: Error, Grade is over 100 End Select

    Stick with integer. Reason: you can have fractional results which break your spec. 80-89 = B ... and 79.67 gets??? 70-79 = C Or you could do the double thing followed by a ROUND operation to get back to integers.
