Given that it takes 1.75 ms to travel from one track to the next of a hard drive; that the arm is originally positioned at track 15 moving toward the low- numbered tracks; and that you are using the look scheduling policy: compute the total seek time to satisfy the following requests—4, 40, 35, 11, 14, and 7. assume all requests are initially present in the wait queue. (ignore rotational time and transfer time; just consider seek time

What a backup plan that you have created in a event you encounter a situation

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.
