ok this is a noobish question. how do u make this program run:

var answer: int
get answer
answer := answer/2
for i : 1..answer
put "Hi"
end for

the error i get is the "answer/2" part. which is because u cant divide an integer by 2 i guess. so i did

var answer: real
get answer
answer := answer/2
for i : 1..answer
put "Hi"
end for

now i get an error at the "for i : 1..answer" part. I'm a turing newbi, plz help.

the second one wont work because the for loop has to count in integers, so if answer is a real it wont work

the first part will only work if the number inputted in an even number

answer := answer/2

it seems like ur trying to divide the answer by 2
so instead do..
code:
answer:=answer div 2

Better yet, use
code:

answer := round (answer / 2)

so that we aren't always rounding down.

Yes, 'div' is only good for things like this if you are going to use 'mod' (remainder) too. I suggest looking at all of the above mentioned solutions in the Turing Help file F9, F10, F11.
