FM>   I am getting a Linker error and it appears to be

FM>       order(ptr+j, ptr+k);
   or more properly, with the line
FM>         for(int j = 0; j < N; j++)
FM>                 cout << arr[j] << " ";
   I don't see any #include  there, do you?? :)
   There may also be a problem with the order() function,
   but I assume that is in another library and part of
   library which accompanies "header.h"?
   It does compile without it. I couldn't link it, of course,
   lacking the "header.h" file and the HEADER.LIB file.
