final in cpp code example
Example 1: final in c++
const int x = 8;
x = 10; // Error. x is final variable now
Example 2: c++ final class
struct Base
{
virtual void foo();
};
struct A : Base
{
void foo() final; // Base::foo is overridden and A::foo is the final override
void bar() final; // Error: bar cannot be final as it is non-virtual
};
struct B final : A // struct B is final
{
void foo() override; // Error: foo cannot be overridden as it is final in A
};
struct C : B // Error: B is final
{
};
