On most platforms (including DJGPP):

  int x;

You can retrieve bit n of integer x by doing this:

  foo = (x >> n) & 1;

If you want to print the binary number, you can loop from n = 31 to 0
to display the number in base 2, or you can use good old itoa().

By "most platforms" I mean the ones that use binary arithmetic for
objects of type `int'.  I challenge comp.os.msdos.djgpp to find an
important computer platform that does not.
