    #include <stdio.h>
    main() {
      int  x, y;
      x = 2; y = 3;
      x <<= 2; printf("\n%3d",x);
      x >>= 1; printf("\n%3d",x);
      x <<= y; printf("\n%3d",x);
      x = 2;
      x &= y;  printf("\n%3d",x);
      x |= y;  printf("\n%3d",x);
      x ^= y;  printf("\n%3d",x);
      printf("\n");
