Introduction Abstract base classes are a powerful tool in object-oriented programming, allowing for the creation of a base class that can be extended by derived classes. However, if an abstract base class contains a parameterized constructor, and the derived class does not, it can be difficult to use the abstract base class. This is because … Read more
No, you can’t. It’s a limitation that says ‘each derived class should use (implicitly or explicitly) at least one constructor from base class. In your example, your child class implicitly has parameterless constructor which implicitly uses parameterless constructor from base. So, you need to: either setup parameretised constructor in every derived class or delele this … Read more
