Today I got a problem. I am in the need of a static member function, const is not a must but a better. But, I didn’t succeed in my efforts. Can anybody say why or how?

When you apply the
constqualifier to a nonstatic member function, it affects thethispointer. For a const-qualified member function of classC, thethispointer is of typeC const*, whereas for a member function that is not const-qualified, thethispointer is of typeC*.A static member function does not have a
thispointer (such a function is not called on a particular instance of a class), so const qualification of a static member function doesn’t make any sense.
