Re: Copy Constructor

Hey guys,

Thank you for your input from the last topic. I tried referencing my c+
+ book and googled the topic but i'am still confused a bit. I have
another problem with that same code. I was hinted what i needed all
along was a copy constructor for class A.

Class B contains a = new A(x) in it's constructor. This is good but
this doesn't make sense. Does that really fit the specs of either
construtors of class A?? So i was brought into the area of making a
copy constructor for class A. This is where i'am having problems i
made one that creates a copy of n but i cannot of x it does not
consider x a member of class A. Do i need to use pointer this?? Code
below.

#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 = new A(x);

        }

      void print ()
       {
         a->print();
         }
       B(const B& copy){ // Class B copy constructor
          a = copy.a;
            //int *p;

            //p = new copy.a;
         }
         const B &operator=(const B x){
          a = x.a; // Operator
         }
         B::~B(){
             delete a;

                }
        };

//---------------------------------------------------------------------=

   int main()
      {

        A a(5);

        B b = a;

        {

            A a1 (7);
            B b1 =a1;
            b = b1;
        }

        b.print();
        cout << endl;
        int trick;
        cin >> trick;
        return 0;
        }

 //--------------------------------------------------------------------=

Thanks guys,
