Fill in the { } such that pi is formatted and using 15 spaces and 5 decimal places, in left, right, center aligned respectively: def left_pi(): left = "Pi is fun to 5 places:{}<-". format (math. pi) return left def right pi(): right= "Pi is fun to 5 places: {}<-". format (math. pi) return right def center_pi(): center= "Pi is fun to 5 places:{}<-".format (math. pi) return center

1)consider the following code snippet: #ifndef book_h#define book_hconst double max_cost = 1000.0; class book{public: book(); book(double new_cost); void set_cost(double new_cost); double get_cost() const; private: double cost; }; double calculate_terms(book bk); #endifwhich of the following is correct? a)the header file is correct as given.b)the definition of max_cost should be removed since header files should not contain constants.c)the definition of book should be removed since header files should not contain class definitions.d)the body of the calculate_terms function should be added to the header file.
