A detailed discussion of c++11 final and override specifiers

As shown below:

//final,override出现在形参列表以及尾置返回类型之后 #include  using namespace std; struct B{ virtual void f1(int) const; virtual void f2(int); void f3(int) final;//出错，final不能修饰非虚函数 }; struct D:B{ void f1(int) const override ;//去掉const将出错，必须和基类中的函数原型一致，否则不能用override来表示覆盖 void f2(int) final;//final说明继承D的派生类中不能覆盖该函数 void f3(); }; struct E:B{ void f2(int);//ok，其直接基类B中该函数没有final说明符 }; struct F:D{ void f2(int);//出错，无法覆盖该函数，原因是其直接基类D中有final说明符 };

final means that the virtual function cannot be overridden, and override means that the function overrides a certain virtual function
