# final Specifier

You can use the **final** keyword to designate virtual functions that cannot be overridden in a derived class. You can also use it to designate classes that cannot be inherited.

## Syntax

```
function-declaration final;
class class-name final base-classes
```

## Remarks

**final** is context-sensitive and has special meaning only when it's used after a function declaration or class name; otherwise, it's not a reserved keyword.

When **final** is used in class declarations, `base-classes` is an optional part of the declaration.

## Example

The following example uses the **final** keyword to specify that a virtual function cannot be overridden.

```cpp
class BaseClass
{
    virtual void func() final;
};

class DerivedClass: public BaseClass
{
    virtual void func(); // compiler error: attempting to
                         // override a final function
};
```

For information about how to specify that member functions can be overridden, see [override Specifier](../cpp/override-specifier.md).

The next example uses the **final** keyword to specify that a class cannot be inherited.

```cpp
class BaseClass final
{
};

class DerivedClass: public BaseClass // compiler error: BaseClass is
                                     // marked as non-inheritable
{
};
```
