RE: keyboard values

Here is a list I have. It is a bit old but I don't think it has changed. Assuming that:

int c;


Then if c = getch(); and the user presses an arrow key, c should return
72 = Arrow up
75 = Arrow left
77 = Arrow right
80 = Arrow down

If you want to see what other keys return, try this:

#include <conio.h>
#include <iostream.h>

int main()
{
    char c, k; // characters for key presses

   while (1)
   {
        // loop forever
        c = getch(); // get a key press
        if (!c)
        {
             // Some keys generate two bytes, the first is a NULL
             k = getch(); //  So we need to get more
             cout << c << ", " << k << endl; // Show what we have, including NULL
         }
         else
         {
             // Otherwise we can just print the key code
             cout << c << endl;
          }
     if (c=='q') break; // Lets get out of here
}


This is some code I picked up off a newgroup several years ago. I haven't tested it on some of the newer compilers so beware.
