Using the new operator

Thanks guys you have been extremely helpful in problems i have come up with.



My latest problem is implementing the New operator. I was able to compile code wth the new operator implemented but All it would do was print a 7 then the rest would be zeros. I  will post the original code below. I'am about to reconstruct the code but i think I i am missing something that would make it simple.

I have class B reference to Class A

Inside the code i'am trying to replace

 B(A & x)
      {
      a = &x;
          }

with a new operator.

#include <iostream>
using namespace std;

class A
{
  int n ;
  public:
   A():n(0)
   {
   }
   A(int x):n(x)
   {
    n = x;
   }

   void print()
   { cout << n<<"\n\n";
   }
 



    A(const A& objectCopy){

            n = objectCopy.n;    // copy constructor

    }


   };

   class B
   {
    A * a;

     public:

    B(A & x)
      {
      a = &x;
  //  x.operator=(x);

        }
    
      void print ()
       {
         a->print();
         }
       B(const B& copy){    // Class B copy constructor
          a = copy.a;
           
         }
         const B &operator=(const B x){
          a = x.a;             // Operator
         }   
         B::~B(){
             delete a;      
            
            
         
                }       
        };

//---------------------------------------------------------------------------
      int main()
      {

        A a(5);
        A a1(7);


        a1.print();
       
        B b(a1);
        b.print();
         B c(a);
         b.print();
         b = c;   
                   
        b.print();
        cout << endl;
        int trick;
        cin >> trick;
        return 0;
        }
         
//--------------------------------------------------------------------------------          





Thanks,
