a Movement doubt in an array

Hi, I would like to know if someone knows how can i move through an array by using the arrow keys, for example my array is

Code:

---

a{2, 3, 5, 64, 7, 34}

---

and the display is 2

them when the user press the right aroow key it automaticaly moves to the second element of the list (so I can modify it if I want) and it prints 3

right arrow key again and it prints 5, then, left arrow and it prints 3, etc

i have been told that I should use the ASCII code and getchar(), however i really have no Idea how to make it work.

thx

I think that using a ASC table you can get the code of the imput you get from the keyboard using something like a getchar then all you need is a switch. Meybe there are more intelligent or easier ways, but I was the first thing that came up to my mind. Go google and look for a ASCII Table

I believe you're looking for getch(). getch() will return a numerical value based on the keyboard key that was hit. I believe, however, that with the arrow keys, it returns two values.

So, if you press an arrow key, I believe the first call to getch() will return a 224, whereas the second call returns the numerical value of the arrow key.....you'll have to do some testing of this on your own, something like so:

Code:

---

int key=getch();
if(key==224)
{
    key=getch();
// process the arrow keys here....and some other buttons
}
else
{
// process the other keys here
}

---

I can't remember exactly if 224 is actually the number that it returns for the arrow keys....so don't quote on me on that, but at least test it out.

-edit-
forgot about the FAQ...it's 224 not 227. Sorry bout that, haven't used getch in ages.

The FAQ has a pretty good article on your problem here.

Ok i'll read the FAQ and also try the getch, thanks.

Any other Ideas will be also really apreciated :D
