   Assuming that the 2's complement system is used to represent the negative
   integers. I wrote the following code , and the results I got were absurd.

C code :

   main()
   {
      int a;
      printf(" Maxint : %d\na = %d\n", ( int )(( unsigned ) ~0 >> 1 ) , 
	      a = ( int )(( unsigned ) ( a = ~0 ) >> 1 ));
   }

 Output :

    Maxint : -1 
    a = 2147483647 

Can some complier writer tell me why this is happening ?
