.....and neither were context diagrams (but that was in the course specifications)

there were so many thigns wrong with that algorithm

all year they've been telling us
"use intrinsic documentation"
"comment your code"
"make your code elegant"

that algorithm goes against everything they've ever tried to hammer into us

for part a i put that if the message header is anythign else, eg if there was an error in transmission or anything, the whole system would shut down. I think i stuffed the second part up because I thought systemstatis was passed on from one of the terminals cos it says inthe text that at the end of the day, the supervisor shuts down the system by entering system status = off

the deskcheck: hey a deskcheck won't help solve such a crappy algorithm. I put down that eventticketsavailable could be negaitve, and that a ticket is issued even if if there are no seats.

i didn't finsih part b

and why did they read system datae and systemtime twice?

 

[sunny]

I had put that down as one of my errors, because the system is supposed to check for the supervisor to change SystemStatus to off to shut the system down, but the loop never checks for it.

Problem is a desk check can't pick something like that up!

2nd error?

i may be completely wrong, but since no one mentioned it, could the 2nd error in the desk check be on line 30 "EventTicketsAvailable = EventTicketsAvailable - NumberTicketsSold" but NumberTicketsSold is a field in TICKET rather than EVENT so it can't be called? Can someone check this please? thx =)

 

[sunny]

Do you mean EventTicketsAvailable is from ProcessEvent so it should be private to ProcessEvent and can't be used in ProcessTicket?

I guess that can be true, cause the exam setters have used STORE and READ on LastEventNumber to use it across different subprograms. Either that or they've just done it to show that the variable should be saved after the program goes offline.

I think any error based on the variables in this algorithm is abit risky, cause if you take the algorithm seriously, where are all those variables the STORE commands are using coming from? Its like they're just plucked out of thin air. If that was taken seriously then this algorithm would have a real problem cause pretty much none of the variables in the program would work since none of them have any value assigned to them.

One guy in my class actually got deparate and put that done as an error.

 

[Mikowizzo]

nono, thats not what i mean. I think they got the variables from a file called EVENT. the OPEN EVENT on line 28 opens the file so they can call the variable EventTicketsAvailable but the NumberTicketsSold is actually a variable in the TICKETS file so they can't call it just by opening the EVENTS file.

 

[sunny]

There shouldn't be any need to read from the file to obtain NumberTicketsSold. All these variables should be passed from the terminals. If it reads the value from a file, then it would be reading the number of tickets that the last transaction processed.

Where is the file being updated to let the algorithm know how many tickets have just been sold? It should be the terminals telling the algorithm what NumberTicketsSold is so that they can be printed.

in that ticket algorithm where we had to sort the algorithm, i didnt have enough time, so i put in my submodule
Begin
sort array
end

do ya recon i will get any marks for that??

i know how to do a bubble sort, but time ran out...

i didnt think the exam was too bad..... and this is coming from one who totally sucks at sofware, mainly because i didnt put the effort in to it ever.... i couldnt be bothered doing much of the algoritm bit, so i concentrated on where i could get more marks rather than waste a good half an hour for something that i would have had gotten wrong anyway.... but hey... no more software EVER for me...

 

[sunny]

eagle, yes you will get some marks cause you have shown that you understand the logic to solving the problem as a whole. But you won't get the full marks.
