What demonstrates that the constructor is called during dynamic object creation?

Overloading the delete operator
Printing out the object's value
Manually calling the destructor
Changing the object's memory address

The correct answer is: Printing out the object's value

Explanation When an object is dynamically created, its constructor is automatically called to initialize the object's member variables and set up its initial state. Printing out the object's value in some form, such as using cout, allows us to see that the constructor has been called and the object has been created successfully. Options A, C, and D are incorrect because none of these actions directly relate to the dynamic object creation process. Overloading the delete operator and manually calling the destructor are related to freeing up memory used by the object, while changing the object's memory address is a low-level implementation detail and does not provide any evidence of dynamic object creation.
