Sorry J.Prius I assumed you knew the questions as it was so easy.
PS- you didn’t know who J.Prius was
well i remember them
- you had to make a procedure to assign data to a file
- the random generator game
- and the last one on arrays and adding up the seconds the sensor was on each date

1. Who the hell is J Prius?

2. The file one was just creating a procedure with parameters including (data and filename)
and then you open the file add the "data" and close the file. Just to be sure, I also asked for an input for the data along with the filename and then called the procedure.

3. Oh random generator, so I used a flow chart which made it so much nicer and easier!!!! Randomly generate two numbers - ask the user for an answer - check if the user_answer is correct to num1 + num2 - if it is then add 1 to score, if not score = score and also tries = tries +1 , when tries = 3, break and exit the loop, at the end display the score.

4. This one, I must admit was difficult at first, so I think I used asked the user for the date and then I used a forloop to check if the date matched a date in the 2D array, for that i did something like arrayevents[x, 0] - I think and to find the corresponding seconds something like [x, 3] and then just added that to the local variable (seconds) I had already created. Then, at the end of the count-controlled loop, I just printed the statement as shown.

There you go, gee I cant think of a famous dude uhm......................Brian Cox, yeah that should do for now.

You're welcome.

For the procedure one I just brought the file name and data as parameters I didn’t get an input but I’m sure it’s fine cause it asked for parameter I think. I opened to file to write. Inserted the data. Then closed the file.

for the number one I used a while loop where questions is not equal to 4. I asked for an answer and checked if it was right by randomly generating a total. Then I incremented the questions.
last one was quite hard I think I got it wrong but I took an input of date. And I used selection and just added whatever position the seconds of that array was. Like if it was 05/03/23 total= array[1,3] plus array[2,3]. Something along those lines
so Elon musk I presume you will get a 9

Well I think that the approach you took for the first 2 six marks is correct - last one, I think you will get marks if you 1. input 2. use a for loop 3. compare dates 4. add seconds 5/6. output result?

Oh well, I am sure you did fine - Neils Bohr!

Can anyone send what they did for the 6 markers

the random number one was probably the easiest so what i did was:

.score = 0
.for i=1 to 3
.. num1 = random(1,10)
.. num2 = random(1,10)
.. ans = int(input("What is "+str(num1)+" + "+str(num2))
.. if ans == num1 + num2 then
... score = score + 1
.. endif
.next i
.print(score)

The file handling one was:

.procudure WhatEverItWasCalled(text,fileName)
.. myFile = open(fileName.txt)
.. myFile.writeLine(text)
.. myFile.close()
.endprocedure

The 2D array one was

.date = input("Enter date")
.time = 0
.for i=0 to 6
.. if arrrayEvents[i,0] == date then
... time = time + arrayEvents[i,3]
.. endif
.next i
.print("The total time on "+date+" was "+str(time)+" seconds")

(Alternatively you could calculate the number of rows in the 2D array as rows = arrayEvents.length / 4 and then do a for loop from 0 to rows-1)

If u also wanted the input validation 6 marker then there were 3 options you could talk about (only had to pick 2). Range check, Presence check, Type check (Length and format check weren't really applicable to the program)
-For a range check the minimum sum was 1+1=2 and the maximum sum was 10+10 so a range check could check the input was from 2 to 20 inclusive
-For a presence check you just have to check the input isn't empty i.e ans.length != 0
-For a Type check you just have to check the inputs were of the integer data type since whole numbers were being added together

(All the code i have given is in OCR referance language and the first 6 mark programming question was in Section A so NOT marked for syntax so all you needed was the logic. For the 2nd and 3rd questions syntax IS marked obviously depending on the programming language of choice)

Score=0
Question=0
While question!= 4 :
F=random(1,10)
G=random(1,10)
Total= F +G
Num=int(input whatever
Question=question+1
If num== total
Score =score +1
Else
Score =score +0

Print(total)
Ignore the Syntax errors but how does this look

I think there's a logic error cuz it will go through the while loop 4 times (cuz Question increments by 1 AFTER asking the question so when asking the 4th question Question = 3 when entering the loop) Looks like 5 out of 6 marks

Regarding some of the other tricky questions the Logic circuit we had to draw was A AND (NOT B) AND C which you could draw in 3 ways: either (A AND (NOT B)) AND C or you could do A AND ((NOT B) AND C) or even (A AND C) AND (NOT B).

the 4 mark programming question about the security system involved more boolean logic

.ActivateAlarm = SystemArmed AND (Windows OR Door)
.if ActivateAlarm then
. SoundAlarm()
.endif

The comparisons of insertion and bubble sort, i put for a difference that insertion sort only requires 1 pass but bubble sort may require multiple passes (so is usually less efficient). For similarities I put that both sort the list from left to right (i.e not divide and conquer) and the runtime for both algorithms depends on how sorted the original list was
