    how to use the keys

    Ok, this is pretty easy. First, you need to define the keys that you want to use:

    #define UP 72
    #define DOWN 80
    #define LEFT 75
    #define RIGHT 77
    #define ENTER 28
    #define ESCAPE 1
    #define CONTROL 29
    #define L_SHIFT 42
    #define R_SHIFT 54
    #define WIN 91
    #define ALT 56
    #define TAB 15

    Now all you need to do is use them as variables for example:

    int Direction=getch();

    if (Direction==UP)
    y++;
