The keyword volatile informs the compiler that a variable may change without the compiler knowing it. Variables that are declared as volatile will not be cached by the compiler, and will therefore always be read from memory.

The keyword mutable can be used for class member variables. Mutable variables are allowed to change from within constant member functions of the class.
