What i think is that dynamic type means dynamically allocated object using new.

Nope.

The dynamic type is the real type of an object that might be accessed via a reference (pointer included) that point to a base type of its real type.

That is, if we have :

class A {

};

class B : public A { };


A* k = new B();

Here k points to an object of type A, but the real type of the pointed object, its dynamic type, is B.

Here "dynamic" has the meaning of "known only at run-time".

That is, if we have :

class B : public A { };


B l;
A& k = l;

Here k is a reference to an object of type A, but the real type of the referred object, its dynamic type, is B.
