In lots of C++ book I have seen they use overload operator '( )' .

I still don't understand when and how to use it.
For example I know how to implement or overload '+' operator for a class or '='. I also exactly know when to use these operators but just cant understand about operator '()'.
Can some please guide me may be by an example. I have googled and I found about tutorials related to overloading .

if essentially turn your class into a functor, ie, you can use it as a function – sp2danny Jul 05 '14 at 16:42
