  #include <stdio.h>
  void main()
  {
      int x, a, b, c, f, z,sum;
      printf ("input x");
      scanf ("%d", &x);
      a = x / 1000;
      f = x % 10;
      b = (x - a * 1000) / 100;
      c = (x - a * 1000 - b * 100) / 10;
      z = f * 1000 + c * 100 + b * 10 + a * 1;
      sum = a + b + c + f;
      printf("a=%d, b=%d, c=%d, f=%d, z=%d, sum=%d",a, b, c, f, z,sum);
  }
