C++11 introduced the final keyword to C++.It can be used on a virtual method or on a class.Declaring a class final forbids any kind of inheritance: public, protected and private.
This question already has an answer here:As per my knowledge, final variables must/can be initialized only once otherwise compiler is supposed to throw an error.
If I have an object which is shared between threads, it seems to me that every field should be either final or volatile, with the following reasoning:
Suppose a class contains a final variable. Why is new space allocated for final variable every time an object of the class is created even though its value can't be changed? Why its memory allocation is not like a static variable?
