Question

Provided the problem statement below, which of the following algorithms will solve the problem?

A student name and three test marks are entered, the average mark must be calculated and it must be determined if the student passes or fails (mark equal or above 50%).  The student name, average and result must be displayed on screen.

Select one:
a.

Function CalcAve (valTest1, valTest2, valTest3)

  return (valTest1 + valTest2 + valTest3) / 3

 

Function DetermineResults(valAve)

  if valAve < 50 then

    message = “fail”

  else

    message = “pass”

  endif

return message

 

ShowResults

  display “Enter the student name”

  enter studentName

  display “Enter the first test mark”

  enter testMark1

  display “Enter the second test mark”

  enter testMark2

  display “Enter the third test mark”

  enter testMark3

  average = CalcAve()

  display “The average mark for “, studentName, “ is “, average

  display “This student will “, DetermineResults()

end

b.

Function CalcAve (valTest1, valTest2, valTest3)

  return (valTest1 + valTest2 + valTest3) / 3

 

Function DetermineResults(valAve)

  if valAve < 50 then

    message = “fail”

  else

    message = “pass”

  endif

return message

 

ShowResults

  display “Enter the student name”

  enter studentName

  display “Enter the first test mark”

  enter testMark1

  display “Enter the second test mark”

  enter testMark2

  display “Enter the third test mark”

  enter testMark3

  average = CalcAve(valTest1, valTest2, valTest3)

  display “The average mark for “, studentName, “ is “, average

  display “This student will “, DetermineResults(message)

end

c.

Function CalcAve ()

  return (valTest1 + valTest2 + valTest3) / 3

 

Function DetermineResults()

  if valAve < 50 then

    message = “fail”

  else

    message = “pass”

  endif

return message

 

ShowResults

  display “Enter the student name”

  enter studentName

  display “Enter the first test mark”

  enter testMark1

  display “Enter the second test mark”

  enter testMark2

  display “Enter the third test mark”

  enter testMark3

  average = CalcAve (valTest1, valTest2, valTest3)

  display “The average mark for “, studentName, “ is “, average

  display “This student will “, DetermineResults(message)

end

d.

CalcAve (valTest1, valTest2, valTest3)

  return (valTest1 + valTest2 + valTest3) / 3

 

DetermineResults(valAve)

  if valAve < 50 then

    message = “fail”

  else

    message = “pass”

  endif

return message

 

ShowResults

  display “Enter the student name”

  enter studentName

  display “Enter the first test mark”

  enter testMark1

  display “Enter the second test mark”

  enter testMark2

  display “Enter the third test mark”

  enter testMark3

  average = CalcAve (valTest1, valTest2, valTest3)

  display “The average mark for “, studentName, “ is “, average

  display “This student will “, DetermineResults(message)

end
