I had about 83 GB before I installed Xcode, I was in the middle of the installation and reconsidered my decision but it's still stuck on 73 GB, any ideas or ways I could probably get my lost space back even though there are no files/folders or applications for Xcode, so I don't know what it is. Thank you!

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
