Std::sort (Vec.begin (), Vec.end (), Func); error C2780: "Void Std::sort (_ranit,_ranit)": You should enter 2 parameters, but provide 3 solutions: Func is a class member function that is changed to a static function at the class's definition.   such as the static bool Func (const type& t1,const type& T2);
