A rolling list of C++ keyword definitions and examples that I've found to be useful.

Links By CPP Keyword

Explicit

Specifies that a constructor or conversion function (since C++11) is explicit, that is, it cannot be used for implicit conversions and copy-initialization.

• Well commented example here: https://en.cppreference.com/w/cpp/language/explicit

Final

Specifies that a virtual function cannot be overridden in a derived class or that a class cannot be inherited from.

• See: https://en.cppreference.com/w/cpp/language/final

Override

Specifies that a virtual function overrides another virtual function.

• See: https://en.cppreference.com/w/cpp/language/override

Virtual

A virtual function a member function which is declared within base class and is re-defined (Overriden) by derived class. When you refer to a derived class object using a pointer or a reference to the base class, you can call a virtual function for that object and execute the derived class’s version of the function.
