Question 28

Given the following pseudocode, which is the argument?

Module main()
Call curveScore(82)
End Module
Module curveScore(Integer score)
Declare Integer newScore
Set newScore= score + 5
Display newScore
End Module

Answer 28

82: bc arguments are always passed as a variable thru the call

Question 29

Given the following pseudocode, which is the parameter?

Module main()
Call curveScore(82)
End Module
Module curveScore(Integer score)
Declare Integer newScore
Set newScore= score + 5
Display newScore
End Module

Answer 29

score: bc module curvescore is being defined using a variable named score

Question 30

Declare Integer newScore
Set newScore= score + 5
Display newScore
End Module

Answer 30

82

Question 31

Given the following pseudocode, what is the value of the score after the call to the curveScore module?

Module main()
Declare Integer myGrade
Set myGrade = 82
Call curveScore(myGrade)
End Module
Module curveScore(Integer score)
Declare Integer newScore
Set newScore= score + 5
Display newScore
End Module

Answer 31

82

Question 32

Given the following pseudocode, what is the value of score after the call to the curveScore module?

Module main()
Declare Integer myGrade
Set myGrade = 82
Call curveScore(myGrade)
End Module
Module curveScore(Integer score)
Declare Integer newScore
Set newScore= score + 5
Display newScore
Set score = 0
End Module

Answer 32

0

Question 33

Given the following pseudocode, what if anything, as an error?

Declare Integer myGrade = 93
Call curveScore(myGrade)
End Module
Module curveScore(Integer score)
Declare Integer newScore
Set newScore = score + 5
Display newScore
Set myGrade = 0
End Module

A) The variable score has not been intialized

B) The variable myGrade is not available inside the curveScore module

C) The curveScore module should recieve a variable named score, not MyGrade
