How would I compare a char to see if it was up, down, left, or right?

(I originally posted this on the Beginners board, but wasn't getting any replies there, so this is a repost)

Say I use getch(), and the person enters the up, down, left, or right key. How would I compare the variable (Let's say the variable is called 'Var') to see if it was one of those keys in an if statement?

and then if you really want to..

though you could just compile

int c = getch();
std::cout << c;

and see for yourself.

I had already tried the cout test, and it would just give an identical unicode-looking character for each one. I'll check out the sites though, thanks!

And yeah, I understand it's terrible for games. It's just that I was working on this a while back, and rediscovering it, really wanted to complete it. Also, I have a problem still. Comparing as

if(Var == 56){}

doesn't work, and neither does VK_UP. I think I am just being extremely ignorant.

conio? I though it was ncurses, sorry.

cast it to int.
0x26 = .38

Edit:

weird. Check if there is an equivalent to keypad or something that needs to be configured.
Post the code, and please be patient

Edit2: from the hamsterman's link:

When reading a function key or an arrow key, each function must be called twice; the first call returns 0 or 0xE0, and the second call returns the actual key code.
