Debugger support for the C++ grammar includes all of the C operators
described in the previous section entitled Operators for the C Grammar.  In
addition to this, the debugger supports a variety of C++ operators which are
described in the C++ Programming Language manual.

Perhaps the best way to illustrate the additional capabilities of the
debugger's support for the C++ grammar is by way of an example.  The
following C++ program encompasses the features of C++ that we will use in
our debugging example.

Example:

     // DBG_EXAM.C: C++ debugging example program

     struct BASE {
         int a;
         BASE() : a(0) {}
         ~BASE(){}
         BASE & operator =( BASE const &s )
         {
             a = s.a;
             return *this;
         }
         virtual void foo()
         {
             a = 1;
         }
     };


     struct DERIVED : BASE {
         int b;
         DERIVED() : b(0) {}
         ~DERIVED() {}
         DERIVED & operator =( DERIVED const &s )
         {
             a = s.a;
             b = s.b;
             return *this;
         }
         virtual void foo()
         {
             a = 2;
             b = 3;
         }
         virtual void foo( int )
         {
         }
     };


     void use( BASE *p )
     {
         p->foo();
     }


     void main()
     {
         DERIVED x;
         DERIVED y;

         use( &x );
         y = x;
     }
