Any difference between const Class& and Class const&?

Is there any difference between that expressions :

const Class&
Class const&

for example, when those are parameters of function ?

Solution

  • There is no difference between const Class& and Class const&; similarly here is no difference between const Class* and Class const*.

    And so, 

    void f1 (const Class& c)

    and 

    void f1 (Class const& c)

    are interchangeable with no difference.

    Both versions denote a reference to a constant Class instance and can be used interchangeably.
