I could easily give you the numbers, but it would be of more benefit to you to create a little test program that uses getch() to get those keys (and others) and print their values to the screen. You can then use those values in your program.

How to define arrow keys in c. 1. Define keys. 2. Put kbhit() in a function. 3. Create a loop. 4. Thats it. Step 1.

#define UP 72
#define DOWN 80
#define LEFT 75
#define RIGHT 77

Step 2.

void pumpKeyboardMessages(void)
{
if (kbhit())
{
ch=getch();
}
}

Step 3.

while (ch!=ESCAPE)
{
pumpKeyboardMessages( );

// Do Other Stuff

}

Step 4. Here's an example of usage:

#include <conio.h>
#include <ctype.h>
#include <stdio.h>
#include <stdlib.h>

#define UP 72
#define DOWN 80
#define LEFT 75
#define RIGHT 77
#define SPACE 32
#define ENTER 13
#define ESCAPE 27
#define TAB 9
#define INSERT 82
#define F1 59

void pumpKeyboardMessages(void)
{
if (kbhit())
{
ch=getch();

switch (ch)
{
    case LEFT:
		//  Do Stuff
	break;

	case RIGHT:
		//  Do Stuff
	break;

	case UP:
		//  Do Stuff
	break;

	case DOWN:
		//  Do Stuff
	break;

	case ENTER:
	break;

	case SPACE:
	break;

	case F1:
 
	break;

	case TAB:
		 
	break;
}

}

}

int main(void)
{
getReady();
initGame();
bas=time(0)+1;
while (ch!=ESCAPE)
{
pumpKeyboardMessages( );

	// Do Other Stuff

} 
return 0;

}
