If you really want to use the !, try:

   if (!((strcmp(argv[1], "-d") || (strcmp(argv[1], "-e")))
      Usage();

since you want the ! to apply to the entire expression consisting of the
two compares.  The code is more readable, however, to avoid negative logic
altogether and just say:

   if ((strcmp(argv[1], "-d") || (strcmp(argv[1], "-e"))
      function();
   else
      Usage();
