benefit of constant member functon

[hellcoder]

is there any benefit (in sense of running time or anything else) to declaring a member function or object as constant?

[vlad from moscow]

The benefit is that you may call a const member function for a const object.:)

[hellcoder]

even we can directly call a constant member function without a const. object!
