I have this snippet of the code and I must write appropriate code with class A (constructor, destructor, copy constructor, operator =), my question is do I need write smart pointers if I want that this code will work perfectly, if no, can you explain where writing smart pointers will be useful, thanks in advance

A *pa1 = new A(a2);
A const * pa2 = pa1;
A const * const pa3 = pa2;

    A smart pointer is not needed, as non of the operations following new can throw. You just need:

    A *pa1 = new A(a2);
A const * pa2 = pa1;
A const * const pa3 = pa2;
delete pa1;

    If this isn’t what you are asking about, please clarify your question.
