And could you provide a sample program that prints on the screen that an arrow key was hit, like I coded my sample program? I am curious about this apparent quick way that you provided.

Also, when I ran it, if I press an arrow key, it displays a lowercase alpha, then the letter you defined. It doesn't detect that an arrow key was pressed (it doesn't say, "You pressed the [insert key here] key!"). I don't know, maybe Dev-C++ does something different. I haven't attempted to look through all of the code yet; it's a little late (early?) and I am not that great at C++ yet.
[EDIT] Wait! you used a lot of c libraries, no wonder, I haven't dealt with those at all... [/EDIT]

Anyways, I was hoping maybe you could explain this error I encountered.

    else
    {
        ch2 = getch();    // get the arrow or function key
        switch(ch2)
        {
                // process the arrow or function key
        }
    }
}

if (kbhit()) { ch1 = getch(); if (ch1 != '\0') { // process a normal keystroke } else { ch2 = getch(); // get the arrow or function key switch(ch2) { // process the arrow or function key } } }

You can use this to discover what the key values are.

This only works for compilers that have getch() and kbhit() defined, of course.
