final = अंतिम

Used in C++ to specify a class that you cannot inherit from.

Example

struct A
{
    virtual void foo() final; // A::foo is final
    void bar() final; // Error: non-virtual function cannot be final
};
 
struct B final : A // struct B is final
{
    void foo(); // Error: foo cannot be overridden as it's final in A
};
 
struct C : B // Error: B is final
{
};
