WebMultiple inheritance allows you to create a derived class that inherits properties from more than one base class. Because a derived class inherits members from all its base classes, ambiguities can result. For example, if two base classes have a member with the same name, the derived class cannot implicitly differentiate between the two members. WebApr 8, 2024 · Most classes aren’t actually intended as bases for inheritance, but C++ permits deriving from any class, unless you write final by hand. Constructors correspond to implicit conversions by default; to get them to behave only like the explicit constructors in any other language, you must write explicit by hand.
