C/C++ Borland C++ 5.0 input using arrow keys

[Ephysics]

hi!
I've started making my own games in Borland C++ 5.0
I want to learn how to detect the user's input of arrow keys (for eg. when a user presses UP,DOWN ,RIGHT or LEFT)
Can somebody please post a short tutorial on detecting arrow keys?
Thank You
Ephysics

PS-
Is this correct ?
int c = getch();
if(c == 0)
{
c = getch();
c*=256;
}

You can't use getch with special keys.
The lib for your compiler needs to have an OS specific function, it's also different if you are in windows or on a console. Look for something like kbhit or conio

I am sorry, I don't understand what you are saying.

On Windows, the special keys form a chain of two characters, beginning with a zero. It is like another page of ASCII characters with an added value of 256.
The following example program compiled with Borland C++ should make this clear.

Compile and run the following program, then you can check the codes required, for example, left/right/down/up arrows have codes 331,333,336,328 respectively with the added 256 to distinguish from the normal ASCII codes. To quit the program, press the escape key (ASCII 27 decimal, octal 33)

#include <stdio.h>
#include <stdlib.h>
#include <conio.h>
int main(int argc, char *argv[]){
    unsigned car=' ';
    do{
        if(car==0)car=getch()+256;
        printf("%ud",car);
    }while((car=getch())!='\033');
    return 0;
}
