Thank so much, it makes Compsci easier, I have a request if you can do more past paper walkthroughs as they really help a lot!

[fitrihanifa]

Thank you so much! so helpful with such a clear explanation. could you explain the use of byref and byval in this as well as in the pseudocode? why are they used?? i don't really get it

[ahadwashere]

thank you so much but can you make a video going through a different types of arrows that can be used in the structure chart

[trbghmi]

We are supposed to write it in the paper right? Or do we need to take our laptop to the exam hall?

[rubennell]

can I use a IF loop at the example at the end because there is only 2 possible steps, volume or surface area so could I write, DECLARE Opperand:CHAR (in the beginning when declaring) And then after CALL InputRadius Output "Do you want to calculate A or V" INPUT Opperand IF Radius <> 0 AND Opperand = 'V' THEN
Answer <- CalculateVolume(Radius)
ELSE
IF Radius <> 0 AND Opperand = 'A' THEN
Answer <- CalculateSurfaceArea(Radius)
ELSE
OUTPUT "Please Enter only a V or an A"
INPUT Opperand
ENDIF
ENDIF
CALL OutputAnswer
