For the relation given, do the following:

state whether the relation is reflexive (2 pts)
state whether the relation is symmetric (2 pts)
state whether the relation is transitive (3 pts)
if the relation is not (reflexive, symmetric, transitive), you must give a counterexample that proves it.

r3 = { (2,3), (3,2) }

4. what is the reason for including the following code snippet in the header file animal.h? #ifndef animal_h #define animal_h class animal { public: animal(); animal(double new_area_hunt); void birth(); void hunt(double new_area_hunt); void death(); double get_area_hunt() const; private: double area_hunt; }; #endif
