#include <iostream>

using namespace std;

// final关键字用于两个地方

// 第一个用在类，用于说明该类是继承体系下最后的一个类，不要其他类继承我，当继承时就会报错。

class Base final {

public:

Base() {}

virtual void func() {}

};

class Derivered : public Base { // error: cannot derive from ‘final’ base ‘Base’ in derived type ‘Derivered’

};

// 第二个用在虚函数，表示这个虚函数不能再被override了，再override就会报错。

class Base1 {

public:

Base1() {}

virtual void func() final {}

};

class Derivered1 : public Base1 {

virtual void func() {} // error: overriding final function ‘virtual void Base1::func()’

};

int main() {

}
