+### Final specifier
+Specifies that a virtual function cannot be overridden in a derived class or that a class cannot be inherited from.
+```c++
+struct A {
+  virtual void foo();
+};
+
+struct B : A {
+  virtual void foo() final;
+};
+
+struct C : B {
+  virtual void foo(); // error -- declaration of 'foo' overrides a 'final' function
+};

+Class cannot be inherited from.

 ### Default functions
 A more elegant, efficient way to provide a default implementation of a function, such as a constructor.
