Can we create a Dynamic Object in C++ if there weren't any default or overload constructors in the class

I want to know whether there's a way of creating dynamic objects if there weren't any Constructors implemented in the class

Yes you can. If you "forget" to define any constructor,then I pretty sure you know that the compiler will create a default one for you.Thus you'll still be able to create objects of that class. If by the phrase "If there weren't any default or *parameterized constructors" you mean that the programmer explicitly deleted all possible constructors,then technically you can still be able to create objects of that class. All you have to do is allocate memory ,either on the stack or on the heap,then reinterpret_cast the buffer's pointer to a pointer of that class. Though honestly I don't know why anyone would want to do this.:-)
