Codaming - Simplified Learning provides smart classroom-type learning by breaking long lectures into short and crisp for each topic.
We explain concepts with examples and pictures for better understanding, moreover we apply the mindmap technique that would definitely help you in connecting the dots and remembering the concepts forever.
We are highly motivated and passionate to provide you high-quality, simplified, and in-depth training at an affordable price.
when we create a pointer of base class and object of derived class we can access the functionality of derived class as well through polymorphism , here without virtual destructor why base class destructor only called ? because the pointer type is base( *b1) so it is destructing the base class. to overcome this we are implementing virtual destructor

Thanks for the great course! It is criminal that this video doesn't have more views, considering it is far better than the other C++ OOP courses. It actually goes in-depth in several places whereas others are kind of shallow. Thank you, sir.
