What are some common inheritance mistakes in C++?

What are some common inheritance mistakes in C++?

Some common mistakes include using public inheritance when private inheritance is more appropriate, forgetting to call base class constructors, and slicing issues when dealing with polymorphism.

Can you explain what slicing issues are?

Slicing occurs when an object of a derived class is assigned to a base class object, leading to the loss of derived class data.

How can I avoid slicing in my code?

To avoid slicing, always use pointers or references to base class types when dealing with derived class objects.

What about virtual destructors? Are they important?

Yes, virtual destructors are crucial in base classes to ensure that derived class destructors are called, preventing resource leaks.
