c = c++ problem

[cvandeso@xxxxxxxx (cvandeso@xxxxxxxx)]

It's exactly done like that !

   c =3D c++;
is treated as
   class C {

     int c =3D 10;
     c =3D inc(); // c is set to 10 again
     int inc() {
       int c_ =3D 0;
       {
         c_ =3D c;
         c  =3D c + 1; // c is set to 11
       }
       return c_; // but c_ is 10
     }
   }
and

   c =3D ++c;
is treated as
   class C {

     int c =3D 10;
     c =3D inc(); // c is set to 11
     int inc() {
       int c_ =3D 0; // temp var
       {
         c  =3D c + 1; // c is set to 11
         c_ =3D c;
       }
       return c_; // and c_ is 11
     }
   }

Well, maybe
   c = c++;
is treated as
   class C {
     int c = 10;
     int inc() {
       int c_ = c;
       c = c + 1;
       return c_;
     }
   }
