computer studies questions

[examman]

what was it about O_O
i want to know the algroithm please

 

[Heshna]

hey guys what did you put for the first algorithm...the one where we had to find errors???

 

[jazzangel16]

Are we actually allowed to discuss it here?? I mean its not 24 hours yet.. The Algorithm was the easiest so far..

 

[Heshna]

I didn't find the algorithm easy...I never understood how to write an algorithm...pffff!!

 

[jazzangel16]

Its going to be 24 hours.. So the errors were

Negative=1
Positive=1
and Print statement being inside the loop
Also the counter value was incremented inside.. though its a for Loop!

I didn't find the algorithm easy...I never understood how to write an algorithm...pffff!!

Start
Count = 0
wsum = 0
hsum = 0
while (count < 1000) do
Input w
Input h
If (h <= 0) or (h = "") or (w <= 0) or (w = "") Then
Output "Error! Try again"
Else
hsum = hsum + h
wsum = wsum + w
count = count + 1
End if
End while
Output ("Average Height:" and (hsum/1000))
Output ("Average Weight:" and (wsum/1000))
End

~~~~~~~~~~~~~~~~~

I'm sad how the algorithm was too easy

..one question was strange!!
euu..real time processing and real time transaction..i dont remember the question well!! :ugeek: :ugeek:
yea algo was ok
the spreadsheet was kind of confusing...
which graph was more appropriate!!>graph A or B??? :geek: :geek:

 

[examman]

come on tell us what the Algorithm question was ... its OK passed the 24hour limit

 

[mimmi]

come on tell us what the Algorithm question was ... its OK passed the 24hour limit

a school was taking weight and height of 1000 students

write an algorithm toL

-input 1000 students weight and height
-calculate the average of height and weight
-output the averages

graph B obviously as the bars with a higher range was closer to the label (100, 200, 300) making it easier to read!

Thanks a lot

total_1 = 0
total_2 = 0
For Counter = 1 to 1000
Input Height
Input Weight
If Input = Weight THEN total_1 = total_1+1
ELSEIF Input = Height THEN total_2 = total_2+1
Next Counter.
Avg_1 = total_1/1000
Avg_2 = total_2/1000
Output
Avg_1
Avg_2

Correct ? xD

You forgot the error part.. We should include an error message so that the height and weight are within a certain limit

Count = 0
wsum = 0
hsum = 0

Output "Error! Try again"
Else
hsum = hsum + h
wsum = wsum + w
count = count + 1
End if
End while
Output ("Average Height:" and (hsum/1000))
Output ("Average Weight:" and (wsum/1000))
End

Umm this should be correct

Correct ? xD

Actually That's not correct =S it's asking for height and weight of all students! If input = weight then... Thingy is wrong as far as what I learned

 

[examman]

according to what i have studied and the question posed by mimmi this is correct

 

[Heshna]

heyyy what was the answer for the graph???????

 

[axhynic]

total_1 = 0
total_2 = 0
For Counter = 1 to 1000
Input Height
Input Weight
If Input = Weight THEN total_1 = total_1+1
ELSEIF Input = Height THEN total_2 = total_2+1
Next Counter.
Avg_1 = total_1/1000
Avg_2 = total_2/1000
Output
Avg_1
Avg_2
Correct ? xD

according to the algorithm, if there is a weight, it would skip the 7th line and will not calculate the height. so if you use just an "IF" instead of "ELSE IF" it should work. you should also include how to catch any errors

 

[Abhiyash]

total Weight=0
total Height=0
For count=1to 1000 do
Repeat Input weight and height
Until weight > 0 and height > o
total weight = total weight + weight
total height = total height + height
Next count
average weight = total weight/1000
average height = total height/1000
Print average weight
Print average height

 

[Heshna]

what was the answer for the question on real time processing and real time transaction???

 

[badshah]

hey.. m gonaa give comp as an additional subject in d next year's oct-nov session,, n ill start stuying it after d may-june session.. so,, is there any way to get easily A* by studyin 3 months only..??
