Call constructors for calling member functions

I am trying to learn C ++ and have to create some code to learn the class hierarchy. It is built in such a way that class A and B have a has-a relationship and class B and C. I need to make a copy of my object in my main file, including the copy constructor A to call the copy constructors in B and C, but I don't know if how to do it.

#ifndef A_HH
#define A_HH


#include "B.hh"


class A {
public:

  A() { std::cout << "Constructor A" << this << std::endl ; }
  A(const A&) { std::cout << "Copy Constructor A" << this << std::endl ; }
  ~A() { std::cout << "Destructor A" << this << std::endl ; }

private:


  B b;

} ;

#endif 

      

        
        
        
      

    

Class B:

#ifndef B_HH
#define B_HH

#include <iostream>

#include "C.hh"

class B {
public:

  B() { std::cout << "Constructor B" << this << std::endl ;  array = new C[len];}
  B(const B& other): array(other.array) { std::cout << "Copy Constructor B" << this << std::endl ; 
   array = new C[len];
    for(int i=0;i<len;i++)
   {
       C[i] = other.C[i];
   } 

  }
  ~B() { std::cout << "Destructor B" << this << std::endl ; delete[] array;}

private:


   C *array;
   static const int len = 12;

} ;

#endif 

      

        
        
        
      

    

And class C:

#ifndef C_HH
#define C_HH

#include <iostream>

class C {
public:

  C() { std::cout << "Constructor C" << this << std::endl ; }
  C(const C&) { std::cout << "Copy Constructor C" << this << std::endl ; }
  ~C() { std::cout << "Destructor C" << this << std::endl ; }

private:

} ;

#endif 

      

        
        
        
      

    

I create both objects like this:

#include<iostream>
#include"A.hh"

int main(){


A a;
A a_clone(a);
}

      

        
        
        
      

    

So, on creation, a_clone

I have to get copy constructor messages, but now it's just creating a new object which I think.

Follow-up question: my class B really looks like the edited one where it should create a dynamically allocated array of objects C

. But this way it still doesn't use the copy constructor. How to fix it?
