const is not used to represent anything. It is reserved, but isn't used.

const is a reserved keyword that is not currently used. Its inclusion as a keyword was to assist compilers in catching out programs where this C++ keyword had been used in error.

final on a reference variable just means that the reference cannot be changed to reference a different object.

As far as I know, const in C++ means that you actually cannot change the object itself (for example by calling mutator methods).

The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
