When to use shared_ptr and when to use raw pointers?

Question

class B;

class A
{
public:
    A ()
        : m_b(new B())
    {
    }

    shared_ptr GimmeB ()
    {
        return m_b;
    }

private:
    shared_ptr&l         


        

Answer 1

1. You allocate B at constuction of A.
2. You say B shouldn't persist outside As lifetime.
   Both these point to B being a member of A and a just returning a reference accessor. Are you overengineering this?
