This is what I wrote, Need someone to tell me weather correct or not.Thankyou.

Set "Distinction" "Mert" "Pass" "Fail"

While mark <= 25 do
Input mark
  If mark >69 than "Distinction"
  if mark >60 AND <69 than "Mert"
  If mark >50 AND <59 than "Pass"
  End if
  Print Distinction Merit Pass Fail

i am sorry but this is completely wrong.......correct answer.....................

i guess its this way
-------------------------------
we take sum, average --> for average...
and as the markscheme says...min and max...too,,,,to compare the values and swap them accordingly..
we limit count to 24 as there are 24 hours in a day..and they want the readings hourly
the markscheme sets the min too 100  and max to 0....because a normal temperature reading for a day (0-50) will fall atlesast in 1 range
============================
sum = 0
min = 100
max = 0
count = 1 (initially)
let the temp be x

for (count=1;count<=24;count +1)
   {
     input x
     F= (x*1.8) + 32
     sum = sum + F
     if F <min, min = F
     if F >max, max = F
(note theres no else)
increment count
                                      }

average = sum/24
print average, max, min

print average, max, min

oh so you just put the counter to 24 and do the rest like usual??
thanks man really helped

hey creatur x ... its not completely wrong..ur logic is still correct..
only minor changes required..

========
Set m, p , d, f

While x <= 25 do (don't use mark again here, use another variable like count)
Input mark
  If mark >69 then then d=d+1
  else if mark >= 60 AND <=69 then m=m+1
  else If mark >=50 AND <=59  then p=p+1
  else f=f+1
  
print m, p, d, f

u identified the result for each student but forgot to count them..u also forgot to include 60 and 50...

[astarmathsandchemistry]

i HAVE THIS FOR CREATURE'S ANSWER..........


Set DISTINCTION, MERIT, PASS, AND FAIL TO 0
SET COUNTER TO 0
While counter is < 25....DO
   Input mark
   Case mark of
         greater than 69=distinction=distinction+1
         greater than 60 or less than 69=merit=merit+1
         greater than 50 or less than 59=pass=pass+1
   otherwise
         Fail=fail+1
   end case
counter=counter+1
end while
PRINT Distinction merit pass or fail


I HOPE THIS IS CORRECT AND IT HELPS

[Ghost Of Highbury]

thats correct rekomeko ... only a few minor changes..
=========
Set DISTINCTION, MERIT, PASS, AND FAIL TO 0
SET COUNTER TO 0
While counter is <= 25....DO
   Input mark
   Case mark of
         greater than 69=distinction=distinction+1
         greater than or equal to 60 or less than or equal to 69=merit=merit+1
         greater than or equal to 50 or less than or equal to 59=pass=pass+1
   otherwise
         Fail=fail+1
   end case
counter=counter+1
end while
PRINT Distinction merit pass or fail

Can anyone tell why do we use firewall?


is this correct answer
firewall is used to prevent any unauthorised programs, users to access our computer?
