can arrow keys be used in C++

Post icon  Posted 29 February 2008 - 05:03 AM

hey guys, is it possible to use arrow keys in C++.
our proffessor wants us to make a 10X10 SOS game (if you know that game, it is similar to tictactoe difference is that instead of straight XXX need to be form the word (s-o-s) should be form instead).

anyway back to the topicl, arrow keys will be used so that the player (user) can choose a box where the letter 'S' or 'O' will be placed. my friend say there is a code/value that is needed. but i don't know what is the value of arrow keys. can any one help about it??? please

Is This A Good Question/Topic? 0

if you are making that on DOS then I think int86() should help you. It generates interrupt and from that you can get the value for key hit. Then map the value to see which key has been pressed [interrupt 22h I guess]. Seems bit difficult :blink:

Or easiest way is write a simple function which uses getch() and gives you the value of key pressed. [This is what I used to do for my assignments]

something like this
        int ch;
        ch = getch();    
        ch = getch();
        printf("\nkey pressed = %d", ch);

now use this code itself to get what are the values for your arrow keys [use mostly for special keys] and use them in your code.

I hope this will help you. :)
