getch() - arrow key representation?

I'm making a small code, and I want my menu to be navigated by the arrow keys or (w, s, a, d). I'm hoping I can do both. I know there has to be an ASCII representation of an arrow key. Or is it interpreted as a different event then a keypress?

I'm using windows XP dos console.



To avoid double-posts I'll ask this here:
Is there any way to center console text? (Other than trial & error spaces?)

No,arrow keys don't have an ASCII value.They are identified by their scan code.Scan code for various keys are

Code:

up-72
down-80
left-75
right-77

You may fetch these keys through following function

Code:

//Returns scan code of key that has been hit
#include<dos.h>
getkey()
{
union REGS i,o;
while(!kbhit());
i.h.ah=0;
int86(22,&i,&o);
return(o.h.ah);
}

Code:

Is there any way to center console text? (Other than trial & error spaces?

Yes,there are 25 rows and 80 columns in dos console.You can calculate it yourself how many tabs you may require to centre your text

So kbhit() can detect arrows?

Also, my compiler is going nuts when I use your code, I'm no good with the (dos.h) library :/. (Borland c++ compiler.)

My Code: (Noob to dos)

Code:

#include <dos.h>

void getkey();

int main() {
 return 0;
}

void getkey() {
 union REGS i,o;
 while(!kbhit());
 i.h.ah=0;
 int86(22,&i,&o);
 return(o.h.ah);
}

Errors:

Code:

You need to say which compiler, if you want to avoid all that old dos crud.

(Borland c++ free command line compiler.)

/\
Thats my compiler. I'm fairly sure its dos library is up-to-date, dont take my word on that though, not totaly sure.

So maybe you should be reading Adrian's win32 console tutorial which is getting a lot of air time at the moment.

Ah tyvm! You guys are great XD.
