Question

5. Write a BASIC program to grade any score entered from the keyboard as either 'Poor' for a score that is below 50% or 'Satisfactory' for a score that is equal to or above 50%. The program execution should stop as soon as a score that is less than zero is entered.

Accepted Answer

10 REM program to grade entered scores
20 CLS
30 Score = 0
40 DO UNTIL Score < 0
50 INPUT "Enter a score:"; Score
60 IF Score < 50 THEN
70   PRINT "Poor"
80 ELSE
90   PRINT "Satisfactory"
100 END IF
110 LOOP
120 END

(Alternative, using SELECT CASE):
DIM Score AS INTEGER
DO UNTIL Score < 0
  INPUT "Enter a score:"; Score
  SELECT CASE Score
    CASE 50 TO 100
      PRINT "Satisfactory"
    CASE 0 TO 49
      PRINT "Poor"
  END SELECT
LOOP
END
