Re: Copy C'tor - doubt

I have a situation where I'm required to generate a copy of an object.
I have simplified the class into a tiny one, but in reality its a huge
class with multiple struct types as data member.

Here is my simplified class:

class AB
{
         private:
                 int a;
         public:

         AB(int ar): a(ar){}

         AB(const AB& arg)
         {
                 a = arg.a;
         }

};

int main()
{
         AB* ab = new AB(7);

         //AB* cd = new AB;

         AB* cd(ab);

         return 0;

}

My Qn is in the statement - AB* cd(ab);

Does object 'cd' uses the same memory as object 'ab' ?

Is any memory allocated in the heap for 'cd' like 'ab' [ I do not
think, maybe I'm wrong ] ?

What happens here exactly.

Thanks in advance friends,
