[syed1995]

multiply dont add *

I was still editing it .. check again .. And yes we are to include m=milk to tell the examiner what m stands for !!

but i would suggest to do it like this ..

m=0 (milk)
y=0 (yoghurt)

and so on.

Khizar read my post above .. you forgot to include the loop !! most important thing.

 

[khizer shahab]

price=price =1 is wrong

sorry it was mistype
price=price+1

 

[syed1995]

Total = 0 (Total Price)
TotalItems = 0 (Total Number Of Items)

REPEAT
Input Item
Read Item
If Item = Milk, than Total = Total +2
If Item = Yogurt, than Total = Total +2.5
If Item = fresh cream, than Total = Total +4
If Item = butter then Total = Total+1
Else Print "Item Not In List"
TotalItems = TotalItems + 1
UNTILL Item = END

If Total > 10 then Total*0.9

Output "Amount In $:" Total
Output "Items Purchased:" TotalItems

Check mine guys .. is it right ?? ^^ Mark it out of 8...

real time transaction involves transaction such as giving money and recieving something on the spot
while real time process control means sensors are involved in maintaining the process...

As quickly as possible, can i have november 2011 papers? both variants.

 

[khizer shahab]

milk = 0
yogurt = 0
fresh cream = 0
butter = 0
count = 1

For count = 1 to n
input item

If item = milk
Then milk = milk + 1

ElseIf item = yogurt
Then yogurt = yogurt + 1

ElseIf item = fresh cream
Then fresh cream = fresh cream + 1

ElseIf item = butter
Then butter = butter + 1

Else Print 'Error'

EndIf

count = count + 1

Next count

Total = 2 * milk + 2.5 * yogurt + 4 * fresh cream + 1 * butter

If Total > 10
Then
Total = 90% * Total

Print Total
Print n


this one is completely correct !!

The loop here is endless ..

how will the computer know when to stop ?? .. n is not an integer, and how will the computer know that nth integer has arrived and it has to move on?

with these types of questions .. our teacher told us that we can only use REPEAT loop .. !!

7/8... Other than the loop everything is perfect!!

in question it is assumed to have n number of items , it isnt a mistake !!! in question the number of item is not given therefore it is assumed!!!

n is any integer, dear

It may be 100, 200 or whatever
The loop would work perfectly fine, dont worry!

You can use For-next, Repeat-until or While-Do
Any loop used will be correct!

 

[syed1995]

Total = 0 ( Total Amount)
m = 0 (Number of Milk)
y = 0 (Number of Yoghurt)
fc = 0 (Number of Fresh Cream)
b = 0 (Number Of Butter)

REPEAT
Input Item
READ Item
If Item = Yoghurt, then y=y+1
If Item=Fresh Cream then fc=fc+1
If Item=Butter, then b=b+1
If Item=Milk, then m=m+1
UNTILL Item = STOP

Total Items = (m+y+fc+b)
Amount = (2*m+2.5*y+4*fc+1*b)

Output "Total Items:" Total Items
Output "Price In $:" Amount
