Assume you are given a boolean variable named issquare and a 2-dimensional array that has has been created and assigned to a2d.

write some statements that assign true to issquare if the entire 2-dimensional array is square meaning every row and column has the same number of elements as every other row and column.

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
