Final answer:
The default constructor is implicitly called when dynamically allocating an object with the new operator. The destructor is not called in this case.
Step-by-step explanation:
When dynamically allocating an object with the new operator, the default constructor is implicitly called. The default constructor is a constructor that is automatically generated by the compiler if no other constructor is defined by the programmer. It initializes the object with default values for its member variables.
For example, let's say you have a class called Person with a default constructor. When you create a new Person object using new Person(), the default constructor will be called, initializing the object with default values for its member variables.
The destructor is called when the object is destroyed and its memory is freed. It is not called when dynamically allocating an object with the new operator.
