how use arrow keys in borland turbo c++ 4.5 (and only this)

hello,
i have a very strange problem.
i wrote a program in "c" in "borland turbo c++ 3.00" "dos version" that uses the ARROW keys.
ARROW KEYS works great in this program, and my program is completely ok in "turbo c++ 3"
but when i copy and paste this program, to "borland turbo c++ 4.5" windows version, ARROW keys don't work on it.there isn't even a single error or warning message.
i am sure this is a problem in borland turbo c++ 4.5.
but i wrote this program for one of my friends and she needs it to work on borland turbo c++ 4.5.
could any one please help to solve this problem.
thanks in advance.
so is there anyway to use arrow keys in version 4.5? (another method).

The "problem" is that you are using an outdated compiler. Therefore you must expect things such as this to happen when you move on to a more modern compiler, even though Borland C++ is still extremely outdated.
Again, why does your friend need it to work on such an outdated compiler?

as a matter of fact , my friend needs this program to work in borland c++ 4.5 because :
she needs to give a representation in class . but the computers there , use only version 4.5
. and i don't think their teacher allows them to use another version.
so this is utterly important to her.

I'd recommend changing school.

As Elysia said, this is outdated and there is no reason to use it any more.

Use a newer compiler like MSVS Express 2010.
