Question

Assume that we have constructor functions for both base class and derived class. Now consider the declaration in

main()

Base *P=New Derived;

In what sequence will the constructor be called?

• A. Derived class constructor followed by Base class constructor
• B. Base class constructor followed by Derived class constructor
• C. Base class constructor will not be called
• D. Derived class constructor will not be called

Answer 1

ans is  B
Here A derived class object is created first and then assigned to a base class pointer. Whenever a derived class object is created, the base class constructor gets called first and then the derived class constructor.
