A question about pointers

[Tony Johansson]

Hello Experts!

I have this statement
Student* john = michael;
where the pointer john is pointing to the same class object that michael is
pointing at.
But now to my question.will the copy constructor for the Student class be
called or any other constructor.

Many thanks.
//Tony

Hello Tony:
The john's type is pointer(not Student) and points to a Student object.
It is nearly the same as int. Its value is an address. Therefore, the
Student's copy constructor will not called. If the code is as the
follow:
Student john = michael;//michael is a Student object. john's type is
Student,not pointer
the Student's copy constructor will be called.
