I have a custom class named videoType. I'm trying to add several videoType objects to a set named videoSet like this:

  set<videoType> videoSet;  
 
  videoType video1("Titanic", 1);
  videoType video2("Star Wars", 2);
 
  videoSet.insert(video1);

When I try to add video1 to the set, I get an error message that points to this line of code in the stl_functions.h file:

/// One of the @link comparison_functors comparison functors@endlink.
  template<typename _Tp>
    struct less : public binary_function<_Tp, _Tp, bool>
    {
      bool
      operator()(const _Tp& __x, const _Tp& __y) const
      { return __x < __y; }
    };

I overloaded all the comparison operators in the videoType class so that the videoType objects can be sorted. Is there something else I need to do to enable the objects to be inserted into the set?

Attached are my files.
videoType.h
main.cpp
